Cart 1 has a mass of m1 = 2.2 kg. Cart 2 has a mass of m2 = 4.2 kg. Cart 1 had an initial speed of v1 = 3.8 m/s and it was initially moving to the right. Cart 2 had an initial speed of v2= 3.2 m/s and it was initially moving to the left. When the two carts meet, they collide with a completely inelastic collision. Find the change in the total kinetic energy of both carts. If the combined kinetic energy of the two carts increased, your answer should be positive. If the combined kinetic energy of the two carts decreased, your answer should be negative. Answer in units of joules.
A ball of mass 2.00-kg is traveling in the positive x-direction at 10.0 m/s and obliquely collides with a 3.00-kg ball that was initially at rest. After the collision, the 2.00-kg ball is traveling at 30.0° above the positive x-axis, while the 3.00-kg ball has a speed of 4.00 m/s. Determine the direction the 3.00-kg ball is moving relative to the positive x direction, and the speed of the 2.00-kg ball.
