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.

Two shuffleboard disks of equal mass, one orange and the other yellow, are involved in an elastic, glancing collision. The yellow disk is initially at rest and is struck by the orange disk moving with a speed of 6.00 m/s. After the collision, the orange disk moves along a direction that makes an angle of 35.0° with its initial direction of motion. The velocities of the two disks are perpendicular after the collision. Determine the final speed of each disk....
