Two balls moving toward one another collide head-on. Ball 1, with mass 0.250 kg, is initially moving to the right with a speed of 2.00 m/s. Ball 2, with mass 0.550 kg, is initially moving to the left with a speed of 1.50 m/s. Immediately after the collision, ball 1 is observed to be moving to the left with a speed of 0.950 m/s.(a) Draw the ‘before’ and ‘after’ scenarios, clearly labelling the known velocities.

In the game of medicine-ball-on-ice, players pass around a medicine ball while they are on ice, which can be assumed to be a frictionless surface. During a game, a 20 kg medicine ball travelling horizontally west at 20 km/h is caught and held by a 50 kg player, who is initially at rest. What is the velocity of the player after she catches the medicine ball?
A 5 kg object, object A, moving at 6 m/s to the right collides head on with a 20 kg object, object B, that is a rest. The 5 kg object ends up with a speed of 2 m/s in the opposite direction. (a) What is the velocity of the second object after the collision? (b) How much kinetic energy is transferred to object B during the collision? (c) How much kinetic energy is lost?
Block A (m=2.5kg) and Block B(m=3.5 kg, to the right of A) move on a frictionless horizontal surface. Initially, Blocl A is moving to the right st 6 m/s and Block B moves to the left with unknown speed. They collide head-on in a perfectly elastic collision. After the collision, block B moves to the right with a speed of 4.5 m/s. A) Find the speed of block B before the collision B)What is the velocity (magnitude and direction) of block A after collision?
A car of mass m_auto = 1.20x10^3 kg travels west-east at a speed of 50.0 km/h, while a wagon of mass m_ wagon = 2.80x10^3 kg travels at a speed of 40.0 km/h in a south-north direction; vehicles collide at an intersection (Point A). From the above and assuming that the crash that occurred is considered a perfectly inelastic collision, determine the magnitude and direction of the velocity that will occur after the collision.
A 1500 kg aircraft going 35 m/s collides with a 2000 kg aircraft that is parked and they stick together after the collision and are going 15 m/s after the collision. If they skid for 123.9 m before stopping, how long (in seconds) did they skid?
Consider a 935 kg car initially moving at 30.5 m/s. a) what is the velocity of the car, in meters per second, just after it hits a 140-kg deer initially running at 12.5 m/s in the same direction? Assume the deer remains on the car.
A 0.00875-kg bullet is fired straight up at a falling wooden block that has a mass of 2.85 kg. The bullet has a speed of 682 m/s when it strikes the block. The block originally was dropped from rest from the top of a building and had been falling for a time t when the collision with the bullet occurs. As a result of the collision, the block (with the bullet in it) reverses direction, rises, and comes to a momentary halt at the top of the building. Find the time t. Number i Units
A block of mass 1.57 kg is placed on a frictionless floor and initially pushed northward, where upon it begins sliding with a constant speed of 5.16 m/s. It eventually collides with a second, stationary block, of mass 3.01 kg, head-on, and rebounds back to the south. The collision is 100% elastic. What will be the speeds of the 1.57-kg and 3.01-kg blocks, respectively, after this collision? 1.62 m/s and 3.54 m/s 3.54 m/s and 1.62 m/s 2.06 m/s and 2.58 m/s 0.65 m/s and 2.10 m/s
A steel ball of mass 0.600 kg is fastened to a cord that is 80.0 cm long and fixed at the far end. The ball is then released when the cord is horizontal.
