QUESTION 3 A ball is projected vertically upwards from the ground next to a building. The ball reaches a maximum height above the ground before moving downwards. On its way down it passes a window 4,2 m tall in the building in 0,4 s. The bottom of the window is 2,2 m above the ground. Ignore the effects of air friction. # 2.2 m (2) 3.1 Write down the acceleration of the ball at the maximum height. (1) 3.2 Write down the magnitude of the velocity of the ball at the maximum height. (3) 3.3 Calculate the velocity of the ball at the top of the window. (4) 3.4 Use equations of motion to calculate the initial speed of the ball (3) 3.5 Calculate the time the ball takes to reach its maximum height above the 4,2 m THI ITAL
