Question

Take zero position to be the drop point and down as the positive direction to answer the following. Make sure that the si of velocity and acceleration are consistent with this coordinate system a tive or negative- your previous nd answers. 5) As the ball falls, the magnitude of its acceleration is 9.8m/s. Should this number be considered negative or positive, given the coordinate system given above? Explain. Assuming it takes one second for the ball to reach the snow, compute the ball's velocity and position when it reaches the surface of the snow. Show your work. 6) 7) As the ball slows down while in the snowdrift, the magnitude of its acceleration is 19.6m/s2. Should this number be considered negative or positive, given the coordinate system given above? Explain. From the time the ball touches the snow, how long does it take to come to rest? Show your work. 8) 9) Compute the ball's position when it comes to rest in the drift. Show your work.

Answer 1

In this problem we have to use equations of motion in straight line when acceleration is constant.
