A 49.0 g marble moving at 2.10 m/s strikes a 21.0 g marble at rest. Note that the collision is elastic and that it is a "head-on" collision so all motion is along a line. What is the speed of 49.0 g marble immediately after the collision? Express your answer with the appropriate units. What is the speed of 21.0 g marble immediately after the collision? Express your answer with the appropriate units.
A 47.0 g marble moving at 2.30 m/s strikes a 26.0 g marble at rest. Note that the collision is elastic and that it is a "head-on" collision so all motion is along a line. What is the speed of 47.0 g marble immediately after the collision? What is the speed of 26.0 g marble immediately after the collision?
A 49 g marble moving at 1.9 m/s strikes a 28 g marble at rest. Assume the collision is perfectly elastic and the marbles collide head-on. Part A: What is the speed of the first marble immediately after the collision? Part B: What is the speed of the second marble immediately after the collision?
A 44g marble moving at 2.0m/s strikes a 20g marble at rest. Assume the collision is perfectly elastic and the marbles collide head-on. What is the speed of the first marble immediately after the collision? What is the speed of the second marble immediately after the collision?
A 50g marble moving at 2.3m/s strikes a 21g marble at rest. Assume the collision is perfectly elastic and the marbles collide head-on. a) What is the speed of the first marble immediately after the collision? b) What is the speed of the second marble immediately after the collision?
Problem 7.41 12 of 15 > Constants Part A A 144-g basebal moving 26 m/s strikes a stationary 5.25-kg brick testing on small rollers so it moves without significant friction. After hitting the brick, the baseball bounces straight back, and the brick moves forward at 1.14 m/s. Determine the baseball's speed after the colision Express your answer to three significant figures and include the appropriate units.

Phys201-1 Summer2020 <A HW (Part 1)Phys201 Problem 7.79 A block of mass m = 2.70 kg starts from the rest and slides down a 300 incline which is 3.60 m high. At the bottom, it strikes a block of mass M-7.50 kg which is at rest on a horizontal surface (Figure 1). (Assume a smooth transition at the bottom of the incline.) The collision is elastic, and friction can be ignored Determine the speed of the block with mass m2.70...
