1. Two asteroids collide head-on and stick together. Before the
collision, asteroid A (mass 1,000 kg) moved at 100 m/s and asteroid
B (mass 2,000 kg) moved at 80 m/s in the opposite direction. Use
momentum conservation (make a complete Momentum chart) to find the
velocity of the asteroids after the collision.
2. Two asteroids identical to those in (1) collide at right
angles and stick together. "Collide at right angles" means that
their initial velocities were perpendicular to each...

Physics Momentum: Car Crash Two cars collide and stick together. The total momentum of a system before a collision is 30,000 kgm/s. If each car has a mass of 1500 kg, what is the magnitude of the velocity of the stuck cars after the collision? a) 20m/s b) 2.2m/s c) 0.05m/s d) 10m/s
Two blobs of clay collide and stick together, moving off at the same velocity. Before the...
Two blobs of clay collide and stick together, moving off at the same velocity. Before the collision, the first blob (m = 1.00 kg) is moving with v = +2.00 m/s and the second blob (m = 2.22 kg) is moving with v = 1.00 m/s. How fast is the combined blob of clay moving after the collision?

Two hockey players are skating on the ice when they collide and stick together. Before the collision the 111 kg defensive player is moving at 1.50 m/s in the West direction, and the 93 kg right wing player is moving at 5.90 m/s at an angle of 27.0° South of Westward. a. What type of collision occurs? Will energy be conserved? b. Find the final velocity of the joined hockey players. Answer in POLAR form. c. Calculate the % of...
