You should pay attention to punctuation, spelling and handwriting. The number of marks is given in brackets at the end of each question or part question. The total number of marks for this paper is Suggestions for how long to spend on each section are given in the booklet. What is RSI? Teenagers interact with different types of media eight hours a day.

Knowing that a worker tosses duffel bag B with an initial velocity of 2. Assuming that the wind velocity is constant during the period of observation, determine the magnitude and direction of the true wind velocity. Determine the speed and the direction of the wind.

With vW now defined, the above diagram is redrawn for the two cases for clarity. If the driver of the automobile traveling north were to stop, at what angle and with what speed would she observe the drops to fall? If the maximum total acceleration of the train must not exceed 1.

Determine the total acceleration of the runner 2 s after she begins to increase her speed. Airplane B is flying at the same altitude as airplane A and, as it rounds a pylon, is following a circular path of m radius. Knowing that at this constant speed the total acceleration of the automobile is equal to one-quarter of its value prior to entering the ramp, determine the maximum value of the total acceleration of the automobile. For the positions shown, determine a the velocity of B relative to A, b the acceleration of B relative to A.

Determine the radius of curvature of the trajectory described by the ball a at Point A, b at the highest point of the trajectory. Determine a the discharge velocity v A of the snow, b the radius of curvature of the trajectory at its maximum height. Determine the radius of curvature of the trajectory described by the coal a at Point A, b at the point of the trajectory 3 ft below Point A.

Express the radius of curvature of the stream at Point B in terms of the magnitudes of the velocities v A and v B. Determine the velocity of the ball at the points of the trajectory described by the ball where the radius of curvature is equal to three-quarters of its value at A. Determine the speed of a satellite relative to the indicated planet if the satellite is to travel indefinitely in a circular orbit km above the surface of the planet.

See information given in Problems After the altitude of the satellite is adjusted, it is found that the time of one orbit has increased by 10 percent. Knowing that the radius of Mars is mi, determine the new altitude of the satellite.

Determine a the velocity and acceleration of the particle at any instant, b the radius of curvature of its path.

What conclusion can you draw regarding the path of the particle? Thus, path is a circle. Determine a the magnitudes of the velocity and acceleration at any instant, b the radius of curvature of the path. The camera is mounted on a mechanism which permits it to record the motion of the car as the car travels on straightway BC. Its flight is tracked by radar from Point A.

Thus, the positive root is chosen. Alternative solution. Determine the magnitudes of the velocity and acceleration of the particle at any time t. Four seconds later, the passenger elevator starts upward with a constant acceleration of 2. Determine a when and where the elevators will be at the same height, b the speed of the passenger elevator at that time.

Assuming that the velocity of the truck is constant during the period of observation, determine the magnitude and the direction of the velocity of the truck. Determine the magnitude of the total acceleration of the automobile after the automobile has traveled ft along the curve. Determine a the initial velocity vA of the stream, b the radius of curvature of the stream as it reaches its maximum height at B.

The radius of curvature of the loop is m.

The plane is being tracked by radar at O. Download pdf. Remember me on this computer. Enter the email address you signed up with and we'll email you a reset link. Need an account?

L' f'IE ; ' e;,,.. For pupils at school, lots of factors play a role in the development of RSI: awkward or fixed positions or stance, the pace of work and repeating tasks can all trigger strain injury.

At home, overusing keyboards, computers, and texting can all cause pain.

Sixty per cent of children who use laptops experience discomfort. More than 42 million texts are sent every day, and consequently mobile phone users are also at risk of injuring their hands. Using predictive text can stop fingers aching because it gives muscles time to rest and recover. What can schools do? At the moment, keyboard skills are not part of the curriculum and only a small number of schools choose to teach the subject in class.

Teaching children the correct way to type and use a computer may help to lessen the number of those who develop RSI.
