Two freight cars, each with a mass of 10000kg collide. One was initially moving at 10m/s while the other was at rest. After the collision they stick together. What is their final speed? O 5m/s O 10m/s O20m/s O 0m/s

Two balls approach each other with equal speeds of 20 m/s. One ball has a mass of 5.0-kg and the other has a mass of 10.0-kg. They collide in a perfectly inelastic collision. The speed of the balls just after the collision is approximately: O 6.7 m/s O 1.3 m/s 30 m/s 0 m/s

A 1500 kg car is rolling horizontally at 2 m/s. You would like to stop the car by shooting a 10 kg blob of sticky clay at it, also horizontally. About how fast should you shoot the clay? O 25 m/s O2 m/s O 150 m/s 300 m/s O 0.01 m/s

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 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

Betty (mass 40 kg) stands in an ice rink as Bubbles (her puppy, mass 12 kg) runs towards her and leaps into her arms. If they move off together with a speed of 0.80 m/s, how fast (in m/s) was Bubbles moving when Betty caught her?

A rock (rock 1) is flying in the sky towards another rock, rock 2. Rock 1 has a mass of 60 kg, and Rock 2 has a mass of 10 kg. Rock 1 is in the sky with a speed of 25 m/s towards Rock 2, and rock 2 is movingtowards Rock 1 in the opposite direction with a speed of 35 m/s. If the two rocks stick together, what is their final velocity? Ignore air resistance and gravity. Is there a change in the kinetic energy of the system? If so, what is it?

Question 6. A diagram of the collision between a moving cue ball and an initially stationary eight ball on a billiards table is given below. The collision of the billiards balls can be considered an isolated system.

A 1200 kg car approaches a 950 kg car that is stopped at a traffic light. The initial speed of the first car is 40 mph, to the right, and it hits the second car. Both stay together moving at the same speed. What final speed do both have? 20 m/s 50 m/s 10 m/s 30 m/s
