Answer one of these two questions in the space below: 1) you and a friend have built a go-cart! your friend pushes you on a level parking lot with a constant force for five seconds, resulting in a final speed of a respectable 15 m/s. you then coast 80 meters to a stop. determine the accelerations for both parts of the trip (assumed constant). also determine the total time of travel and the total distance traveled. 2) a machine launches a tennis ball with an initial vertical velocity of 9.0 m/s and an initial horizontal velocity of 4.5 m/s. determine the magnitude and direction of the initial velocity vector. determine the range of the tennis ball (the horizontal distance the ball would travel if it was launched on a level surface) and the maximum height. finally, determine the position of the ball (x. y) at 1.25 seconds.
