Consider two lumps of clay (A and B) moving towards each other at a speed of v (v is relative to the ground). If clay A has a mass 3.1 times greater than clay B, what fraction of kinetic energy is lost after collision? Express your answer in decimal form with two decimal places.A 2.00-kg object traveling east at 20.0 m/s collides with a 3.00-kg object traveling west at 10.0 m/s. After the collision, the 2.00-kg object has a velocity 5.00 m/s to the west. How much kinetic energy was lost during the collision? O 0.000 J O 175 J O 91.7J O 458 J 516JA 620-g object traveling at 2.1 m/s collides head-on with a 320-g object traveling in the opposite direction at 3.8 m/s. If the collision is perfectly elastic, what is the change in the kinetic energy of the 620-g object? O It loses 1.4 J. It loses 0.23 J. O It loses 0.47 J. It gains 0.69 J. It doesn't lose any kinetic energy because the collision is clastic.During a collision with a wall, the velocity of a 0.200-kg ball changes from 20.0 m/s toward the wall to 12.0 m/s away from the wall. If the time the ball was in contact with the wall was 60.0 ms, what was the magnitude of the average force applied to the ball? O 40.0 N 107 N 13.3 N 26.7 N 16.7 NA point particle of mass 3.95 kg is moving with an initial velocity of 2.85 m/s ?. It collides and sticks to an object of mass 4.43 moving at velocity of -1.29 m/s } before collision. What is the speed of the particles after collision? Express your answer in m/s and with two decimal places.A 0.014-kg bullet is fired into a stationary block of wood of mass of 4.9 kg. The relative speed of the bullet with respect to the wood is zero after collision (The bullet becomes embedded on the block of wood). If the speed of the bullet before collision is 473 m/s, what is the kinetic energy of the bullet-plus-wood combination right after the collision? Assume no change in the potential energy of the system before and after the collision. Express your answer in two decimal places, in Joules
