A 2.0-kg mass moving at 5.0 m/s suddenly collides head-on with a 3.0-kg mass at rest. If the collision is perfectly inelastic, what is the speed of the masses just after the collision? 2.5 m/s 10 m/s 2.0 m/s 0 m/s, since the collision is inelastic
A 5.0 kg object with a speed of 4.0 m/s collides head-on with a 10 kg object moving toward it with a speed of 5.0 m/s. The 10 kg object stops after the collision. a) What is the post collision speed of the 5.0 kg object? b) Is the collision elastic? c) What is conserved?
A 5.00 kg frictionless puck travelling at 8.00 m/s collides with another of mass 3.0 kg which is travelling in the same direction at 4.0 m/s. They remain stuck together after the collision : What is their speed after the collision?
A puck of mass 0.70 kg approaches a second, identical puck that is stationary on frictionless ice. The initial speed of the moving puck is 5.0 m/s. After the collision, one puck leaves with a speed vi at 30° to the original line of motion. The second puck leaves with speed v2 at 60°. (a) Calculate V1 and v2. Vi = 866025 x Vy = 250011 x m/s m/s (b) Was the collision elastic? Yes No eBook
5. Ball 1 has a mass of 2.0 kg and is suspended with a 3.0 m rope from a post so that the ball is stationary. Ball 2 has a mass of 4.0 kg and is tied to another rope. The second rope also measures 3.0 m but is held at a 60.0° angle, as shown in Figure 7. When ball 2 is released, it collides, head-on, with ball I in an elastic collision. (a) Calculate the speed of each...
