Block A of mass mA=6kg ,slides down an incline from a height of 10 m from the ground. Block A then collide with block B, with a mass mB=8kg which is at rest in the ground. The collision is elastic. There is no friction between the blocks and the incline nor between the blocks and the ground.

a) Find the velocity of A before it collides with B ( 5 points)

b) Find the maximum height that block A climbs up in the incline after the collision (10 point)

block 1 of mass m1 slides from rest along a frictionless ramp from an unknown height h and then collides with stationary block 2, which has mass m2 = 3m1 . The collision is an elastic one. After the collision, block 2 slides into a friction-filled region where the coefficient of kinetic friction is 0.5 and comes to a stop through a distance d = 10 m in that region. What is the height h?

Consider the following two blocks A and B with the mass of ma= 7 kg and mb = 4 kg. They are moving in the same direction along the x-axis on a horizontal frictionless surface with initial velocities vai= 30 m/s and vbi= 20 m/s. The two blocks collide head-on and there is no change in the line of motion of either object. If the collision is elastic, find the final velocity of block A.
