Two carts collide on a level track. Cart A has a mass of 203 g and Cart B has a mass of 277 g. Before the collision Cart A is traveling to the right at 30.3 cm/s and Cart B is traveling to the left at 6.00 cm/s. After the collision, Cart B is moving to the right at 12.1 cm/s. What is the velocity of Cart A after the collision? (make sure to include the direction on your written work) cm/s

A girl of mass 47.0 kg jumps off the bow of a 66.0-kg canoe that is initially at rest. If her velocity is 1.90 m/s to the right, what is the speed of the canoe after she jumps?

A 1200-kg car moving at 15.6 m/s suddenly collides with a stationary car of mass 1500 kg. If the two vehicles lock together, what is their combined velocity immediately after the collision? 5.5 m/s O 8.6 m/s O 6.9 m/s O 12.1 m/s

A.16 kg marble moving to the right at 1.2 m/s has  a head-on elastic collision with another ball of equal mass moving to the left a .85 m/s. The first ball moves to the left at .85 m/s after the collision.  Find the velocity of the second ball after the collision.  Include the units, put a space between the numerical answer and the units.  Round to the nearest tenth

Please help me understand the concept of this practice problem and how to work these types out. Thanks

Two cars each with a speed of 30 m/s are sliding on frictionless ice at an intersection and collide. Car #1 has mass 1400 kg and Car#2 has mass 1300 kg. The cars stick together after colliding. A) What is the angle the combined mass comes off the collision at ? B)What is the speed of the combined mass?

A car of mass 2000 kg traveling east at 20 m/s strikes a 3500 kg truck traveling west at 10m/s. The car and truck lock bumpers and stick together. What are the final speeds of the car and the truck ?

An object with a mass of 8.00 g is moving to the right at 14.0 cm/s when it is overtaken by an object with a mass of 25.0 g moving in the same direction with a speed of 17.0 cm/s. If the collision is elastic, determine the speed of each object after the collision in centimeters per second. 25.0 g object_______________ cm/s   8.00 g object _______________ cm/s

In the railroad freight yard, an empty freight car of mass m rolls along a straight level track at 1.20 m/s and collides with an initially stationary, fully loaded boxcar of mass 5.80m. The two cars couple together on collision.   a.)What is the speed of the two cars after the collision? b.)Suppose instead that the two cars are at rest after the collision. With what speed was the loaded boxcar moving before the collision if the empty one was moving at 1.20 m/s?

Please have answers computer typed.
