A 1000 kg car moving at 20 m/s collides with a 3000 kg truck ,moving toward it also at 20 m/s. After collision the truck stops. What is the velocity of the car?

Problem 5: A 1.8 kg falcon catches a 0.65 kg dove from behind in midair. What is the speed of the pair of birds right after the catch if the falcon's initial speed was 28 m/s, the dove's initial speed was 7 m/s, and they were moving in the same direction?

A 43kg is standing near and to the left of a 54kg boy, both on frictionless stationary skate boards. The boy throws a .85 kg bag at 7.1 m/s. What is the velocity of the boy after he releases the bag?  What is the velocity of the girl after she catches the bag?

A truck with a mass of 1600 kg and moving with a speed of 13.5 m/s rear-ends a 585 kg car stopped at an intersection. The collision is approximately elastic since the car is in neutral, the brakes are off, the metal bumpers line up well and do not get damaged. Find the speed of both vehicles after the collision in meters per second. V car 6.27 m/s V truck = 19.77 X m/s

3. Bob and Linda are sweethearts that enjoy skating arm in arm. Bob has a mass of 85 kg and Linda has a mass of 60 kg. Initially they are skating together with a speed of 3.0 m/s. Then Bob whispers a dirty joke into Linda's ear, causing her to push him in the oppposite direction of their motion. If Bob's final speed is 1.0 m/s, what is Linda's final speed? Before: Vi After: VBÍ

A 2,300-kg car moving east at 10.0 m/s collides with a 3,000-kg car moving north. The cars stick together and move as a unit after the collision, at an angle of 33.0° north of east and at a speed of 5.17 m/s. Find the speed of the 3,000-kg car before the collision.

A 1.825-kg falcon catches a 0.570-kg dove from behind in midair. What is their velocity after impact if the falcon’s velocity is initially 28.5m/s and the dove’s velocity is 8.0m/s in the same direction?

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

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?

A 180-g golf club is moving at 35.0 m/s when it strikes a 50.0-g golf ball and sends it off at 45.0 m/s.   A) Determine the speed of the club after the collision. B) If the impact lasted for 5.00 ms, determine the average force exerted on the ball by the club.
