Question: PART B: Problems (5 marks each: total of 30 marks) 1. A 1.0 kg football is given an initial velocity at ground level of 20.0

PART B: Problems (5 marks each: total of 30 marks) 1. A 1.0 kg football is given an initial velocity at ground level of 20.0 m/s [37 above horizontal]. It gets blocked just after reaching a height of 3.0 m. (A) (a) What is the velocity of the football when it first reaches a height of 3.0 m above the level ground? (b) What horizontal distance has the ball travelled when it first reaches a pg. 2 USCA ACADEMY SPH4U FINAL EXAM height of 3.0 m above ground? 2. The blocks in the system illustrated below are moving such that block A is moving up the ramp. The coefficient of kinetic friction between the ramp and the sliding block is 0.11. Determine the magnitude of acceleration of the blocks below and the magnitude of force of tension in the string. (A) B 2.0 kg 3.0 kg A 350
