A 4800-kg truck traveling with a velocity of +4.0 m/s collides head-on with a 1200-kg car have traveling with a velocity of -12 m/s. The truck and car entangle and move together after the collision. Fill in the before- and after-collision table below. Momentum Before Collision Momentum After Collision Momentum Change Truck 4ms -12ms Total -8 Determine the veloaty of the truck and car immediately after the collision PSYW

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.

the rearrangement of particles in a physical change. hope this

it is b. absorbs thermal energy
