Problem 4 30 Points Disk A Ma 2 Kg Is Moving Toward Disk B Mg 2 Kg Located At D 5 M Away On A Horizontal Surface 1 (50.95 KiB) Viewed 57 times

Problem 4 (30 points) Disk A (ma=2 kg) is moving toward disk B (mg=2 kg) located at d=5 m away on a horizontal surface. Velocity of A is VA=10 m/s and 0=30°. The coefficient of kinetic friction between the disks and the surface is p=0.3. Disk B can only move inside the tube and is attached to the wall on the right via a spring with k=200 N/m. front ده B 이 5 m (a) Find the velocity of disk A immediately before it hits disk B. (b) Find the velocity of both disks immediately after the impact if coefficient of restitution is e=0.8. (ignore the friction during the impact) (c) Find the maximum compression in the spring if it is un-stretched before the impact.
