A 1200 kg car traveling initially with a speed of 25 m/s in an easterly direction crashes into a 9000 kg truck moving to the west at 20 m/s. The velocity of the car after collision is 15 m/s to the west. Calculate the magnitude of the speed of the truck after the collision.

Two cars approach an ice-covered intersection. One car, of mass 1.10  103 kg, is initially traveling north at 10.1 m/s. The other car, of mass 1.55  103 kg, is initially traveling east at 10.1 m/s. The cars reach the intersection at the same instant, collide, and move off coupled together. Find the velocity of the center of mass of the two-car system just after the collision. Magnitude:

A truck with a mass of 1320 kg and moving with a speed of 12.0 m/s rear-ends a 703 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 m/s %3D Vtruck m/s Additional Materials

A 200 kg cannon rests on a smooth surface. It fires a 10 kg cannonball in horizontal direction. The cannonball moves with a velocity of 200 m/s measured relative to the cannon right after the firing. Determine the speed of the cannon after the fire.

A 0.250 kg toy car moving with a speed of 0.860 m/s collides with a wall. The figure shows the force exerted on the car by the wall over the course of the collision. What is the magnitude of the velocity, or final speed, of the car after the collision?

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

Two blocks of masses m, = 2.00 kg and m, = 3.70 kg are released from rest at a height of h = 5.90 m on a frictionless track as shown in the figure below. When they meet on the level portion of the track, they undergo a head-on, elastic collision. Determine the maximum heights to which m, and m, rise on the curved portion of the track after the collision. hm1= hm2= m

A knife thrower throws a knife toward a 300 g target that is sliding in her direction at a speed of 2.30 m/s on a horizontal frictionless surface. She throws a 22.5 g knife at the target with a speed of 38.0 m/s. The target is stopped by the impact and the knife passes through the target. Determine the speed of the knife (in m/s) after passing through the target.

A 1425 kg truck driving at 13.0 m/s collides elastically with a stationary 1175 kg car. If the car is traveling 14.25 m/s just after the collision, what is the velocity of the truck immediately after the collision? Assume that this is a perfectly elastic collision. Round your answer to the hundredths place. Final velocity of the truck = m/s

Two toy cars with masses of 0.70 kg  and 0.30 kg, respectively, move towards each other and collide  head-on and then stick together.. The magnitude of the initial velocity for each of of the toy cars is 15.0 m/s. What is the speed of the toy cars  immediately after collision?
