A 0.30kg cart moves on an air track at 1.2 m/s. It collides with and sticks to another cart of mass 500 kg, which was stationary before collision. What js the velocity of the combined carts afters collision?

A 1000-kg car approaches an intersection traveling north at 20.0 m/s. A 1200-kg car approaches the same intersection traveling east at 22.0 m/s. The two cars collide at the intersection and lock together. Ignoring any external forces that act on the cars during the collision, what is the velocity of the cars immediately after the collision? 15.1 m/s in a direction 52.8° east of north O 21.1 m/s in a direction 47.7° west of south O 21.1 m/s in a direction 47.7° east of north O 29.7 m/s in a direction 47.7° east of north O 21.1 m/s in a direction 52.8° east of north

A 0.145 kg baseball is pitched at 42 m/s to the right. The batter hits it horizontally to the pitcher at 58 m/s.(Zitzewitz et.al., 2006)A. Find the change in momentum of the ball.B. If the ball and bat are in contact for 4.6x10¯ 4 s, what is the average force duringthe contact?

An 250 kg bumper car going 15.9 m/s has a 1d elastic collision with a 200 kg stationary bumper car.  How fast would the 200 kg bumper car be going after the collision in m/s?

What is the velocity of a 900-kg car initially moving at 30.0 m/s, just after it hits a 150-kg deer initially running at 12.0 m/s in the same direction? Assume the deer remains on the car. What type of collision is in this problem? elastic, inelastic, plastic, deadly

A 1 295.0 kg car traveling initially with a speed of 25.000 m/s in an easterly direction crashes into the back of a 8 900.0 kg truck moving in the same direction at 20.000 m/s. The velocity of the car right after the collision is 18.000 m/s to the east. VTS Before After (a) What is the velocity of the truck right after the collision? (Give your answer to five significant figures.) × m/s east 4.0 (b) What is the change in mechanical energy of the car-truck system in the collision? Your response differs from the correct answer by more than 10%. Double check your calculations. J (c) Account for this change in mechanical energy.
