Two large balls roll over a smooth surface and collide. They are made of a super hard material so there is no deformation. Ball 1 has a mass ?1 of 2.00 ?? and travels with an initial velocity of 10.0 ?/?. Ball 2 has a mass ?2 of 5.00 ?? and travels with an initial velocity of 1.42 ?/?. A tracking system captures the collision data and is shown below. After the collision, what are the speeds of the two balls?

Two balls on a frictionless plane are heading towards each other. Ball 1 has a mass of 2 kg and is heading to the right at 3m/s,and ball 2 has a mass of 5 kg and is heading to the left at 1m/s. Both balls collide into each other, but their centers are slightly off-center resulting in a change of ball 1’s trajectory from parallel to the x-plane to 70° above the x-plane. What are the magnitude and direction of...

A ball, m1 = 0.1 kg, having initial velocity v1i = 0.5 m/s hits a stationary ball in a glancing collision. After the collision the balls have final speeds v1f = 0.4 m/s and v2f = 0.2 m/s and ball 1 bounces back at an angle of 110 degrees relative to its incident trajectory. a) Sketch diagrams of the balls before and after the collision. Include a co-ordinate system and label all relevant angles and velocities. b) Write down algebraic...

Two metal balls of equal mass collide elastically (what does this mean in terms of conservation?), with the collision happening at the origin. The second ball starts out at rest at the origin, and the first ball starts out approaching the origin with some velocity, moving entirely in the positive x direction. The second ball ends up traveling at 12 m/s, moving in a direction that is 60 degrees above the positive x axis. Find the final velocity (magnitude and...

Two balls traveling in opposite directions collide head on. Ball1 is traveling in the positive x direction at a speed of v1 = 4.50 m/s and mass of m1 = 2.0 Kg. Ball2 is traveling in the negative x direction at a speed of v2 = -6.50 m/s and a mass of m2 = 4.0 Kg. a) If we assume that the two balls are made of clay and become one mass during the collision what is their combined final...

2 tennis balls slide in a horizontal direction towards each other. Tennis A has mass of 0.25 kg and velocity of 10 m/s. Tennis Ball B has a mass of .035 kg and initial velocity of 26 m/s. Eventually both tennis ball collide and Tennis Ball B has speed of 6m/s at angle 150. Solve for the velocity magnitude and direction after the collision.

A ball with a mass of 2 kg is initially moving to the right with a speed of 3 m/s. It collides with a 5 kg ball moving to the left with a speed of 1 m/s. The balls collide partially elastically: 70% of the initial kinetic energy of the system is conserved in the collision. Find the final velocity of each ball. The balls move only along the x-axis.
