PHYS 1301W Lecture 1: Collisions and Angular Displacement
Document Summary
1000-kg car is pulling out of a driveway at a speed of 8 m/s, colliding with a 2000-kg van which came from the left at 15 m/s. The cars are stuck together after the collision. Determine the direction into which the cars have been moving right after the collision. Find the amount of energy spent in damage. On a pool table, ball 1 is striking the resting ball 2 with an initial velocity v1=2. 0 m/s. The masses of the balls are 100. 0 g. after the collision, the balls move away both at the same angle with respect to the original direction. The distance between the center of the earth and the moon is 384000 km. Find the location of the center of mass of the earth moon system. Knowing a revolution period of the moon around the earth to be 28 days, find the tangential velocities of moon and earth around their center of mass.
