Question

please answer quizkly and correctly, thanks

A 20kg-block is released from rest at A. The block slides along the rough surface ABC to hit a 4 kg ball, which is initially at rest at C. The ball then starts sliding up along a smooth curved surface CD and eventually leaves point D in a projectile motion. The coefficient of kinetic friction between the block and the surface ABC is lk= 0.2. The coefficient of restitution between the block and the ball is e = 0.5. The distances are: LBC = 8m, LAB=25m. If the ball reaches point D with a velocity of Vp=18 m/s: For the projectile motion initiated at point D, determine the flight of time tpE from D to E. Vp Block 0-600 0-60° D a=150 Ball E B=60°/ LAB y -LBC
