A 9,700-kg truck runs into the rear of a 1,000-kg car that was stationary. The truck and car are locked together after the collision and move with speed 2 m/s. Compute how much kinetic energy was "lost" in this inelastic collision in J.

A 3,400-kg truck runs into the rear of a 1,000-kg car that was stationary. The truck and car are locked together after the collision and move with speed 2( m)/(s). Compute how much kinetic energy was "lost" in this inelastic collision.

A 500Kg Ford focus automobile is initially travelling at vi, focus=(60i + 20j)Km/hr when it inelastically collides with a 16.7Mg semitruck initally traveling at vi,truck=(-30i-110j)Km/hr. problems: a) what is the final velocity immediately after the inelastic collision?  b) assume that, just after the collision , the ford focus and semitruck begin to slide across the pavement due to a uniform kinetic friction with coefficient uk=0.45. how far will they slide before coming to a stop.

A railroad car of mass 3.50 x 104 kg moving at 2:70 m/s collides and couples with two coupled railroad cars, each of the same mass as the single car and moving in the same direction at 1.20 m/s. (a) What is the speed of the three coupled cars after the collision? 3 m/s (b) How much kinetic energy is lost in the collision? Need Help? Read It Viewing Saved Work Revert to Last Response

A small block of mass M is released from rest at the top of the curved frictionless ramp shown in the figure. The block slides down the ramp and is moving with a speed of 3.50 m/s when it collides with a larger block mass 1.5M at rest at the bottom of the incline. The larger block moves to the right with a speed of 2m/s immediately after the collision. Express your answer in speed of the small block after the collision in terms of the given quantities and fundamental constants. ... 1.5M 2 M - 1.50 A V small block M ЗМ— 1.50M в) V small block M 3.50 (m/s) M-3(m/s)M © v V small block M 3.50 (m/s) M- 1.50(m/s) M D V small block M

A curiosidade child stands on the top of a 670 m Skyscraper  and Drops a coin from the top of the building. How fast is the coin moving when it hits the ground. Solve using conservation of momentum

A 480-kg car moving at 16.4 m/s hits from behind a 570-kg car movingat 13.3 m/s in the same direction. If the new speed of the heavier car is 14.0 m/s,(a) what is the speed of the lighter car after the collision, assuming that anyunbalanced forces on the system are negligibly small, and(b) what average power is dissipated during the collision if they collide for 1.4seconds?

A 25-kg box of books is dropped on the floor from a height of 1.1 ? and comes to rest. What impulse did the floor exert on the box?

You have a mass of 72kg. If you slide on ice at 3.6m/s to greet a 40kg friend who is standing still. As you collide while holding hands what would be there speed do you both move off together

A 0.500 kg block of cheese sliding on a frictionless tabletop collides with and sticks to a 0.200 kg apple. Before the collision the cheese was moving at 1.40 m/s and the apple was at rest. The cheese and apple then slide together off the edge of the table and fall to the floor 0.600 m below. (a) Find the speed of the cheese and apple just after the collision. In this collision, what is conserved: momentum, total mechanical energy, both, or neither? (b) What is the speed of the cheese and apple just before they hit the floor? During the fall from the tabletop to the floor, what is conserved: momentum, total mechanical energy, both, or neither?
