Two spheres with masses of 3kg and 5kg move towards one another each travelling at a speed of 29m/s. They collide by direct impact. If the coefficient of restitution between the two spheres is 0.85 calculate the speed of the 3 kg sphere (in m/s) immediately after the collision.

Two titanium spheres approach each other head-on with the same speed and collide elastically. After the collision, one of the spheres, whose mass is 250 g, remains at rest. (a) What is the mass (in g) of the other sphere? (b) What is the speed of the two-sphere center of mass if the initial speed of each sphere is 4.5 m/s?

One object is at rest, and another is moving. The two collide in a one-dimensional, completely inelastic collision. In other words, they stick together after the collision and move off with a common velocity. Momentum is conserved. The speed of the object that is moving initially is 30 m/s. The masses of the two objects are 3.0 and 7.6 kg. Determine the final speed of the two-object system after the collision for the case (a) when the large-mass object is...

Two insulating spheres have radii 0.300 cm and 0.500 cm, masses 0.500 kg and 0.700 kg, and uniformly distributed charges of -2.00 µC and 3.00 µC. They are released from rest when their centers are separated by 1.00 m. (a) How fast will each be moving when they collide? (Hint: Consider conservation of energy and of linear momentum.) m/s (lighter sphere) m/s (heavier sphere)

Consider an inelastic collision between two spheres of different masses, m1= 1kg and m2=3 kg, in the +x direction. Ball M1 is moving at speed, v1=3.0ms, and ball 2 is moving towards ball 1 at speed, v2=1 kg. 1. What will happen to the velocities of the two balls after a completely inelastic collision? Explain your reasoning. Do NOT do any calculation yet. Use your physical intuition and what know so far about collisions. 2. Which physical principles were used...

An experiment is performed in deep space with two uniform spheres, one with mass 20.0 kg and the other with mass 108.0 kg . They have equal radii, r = 0.30 m . The spheres are released from rest with their centers a distance 40.0 m apart. They accelerate toward each other because of their mutual gravitational attraction. You can ignore all gravitational forces other than that between the two spheres. A. When their centers are a distance 28.0 m...
