Question 4 a) Robert throws his mother's crystal vase vertically upwards with an initial velocity of 26.2m/s. Determine the height to which the vase will rise above its initial height. b)

with what speed in miles/hr (1m/s = 2.23mi/hr) must an object be thrown to reach a height of 91.5m (equivalent to one football field)? Assume negligible air resistance. c) A ball is kicked at an angle = 45°. It is intended that the ball lands in the back of a moving truck which has a trunk of length L = 2.5m. If the initial horizontal distance from the back of the truck to the ball, at the instant of the kick, is d = 5m, and the truck moves directly away from the ball at velocity V = 9m/s (as shown on the next page), what is the maximum and minimum velocity vo so that the ball lands in the trunk? Assume that the initial height of 2/nthe ball is equal to the height of the ball at the instant it begins to enter the trunk. Vo do L
