FORCES AND 115 exerted on the wall? After the collision, what are their velocities after collision? A Ina wedding a bullet is fired in air at a speed of 500 m/s making an angle of 60° with horizontal from an AK 47 rifle. (a) How high will the bullet rise? (b) What time would it take to reach ground? (c) How far would it go? (lgnore air resistance) ((a) 9,560 m (b) 88.3 s (c) 22,078 m) The catapult hurls a stone of mass 32.0 g with a velocity of 50.0 m/s at a 0.0 angle of elevation. (a) What is the maximum height reached by the it returns to its original height? ((a) 31.87 m (b) 5.1 s (c) 220.8 m)
