Two pendulums have the same length but different masses. If m1 is released from the position shown in the figure on the right, how high would the masses reach after the collision (a) assuming a perfectly inelastic collision, and (b) perfectly elastic collision. Use m1(green) = 100g, m2 (purple) = 150g, and angle = 40 degrees, Length 1 & 2 = 0.5 m.

Two blocks of masses m1= 2.00 kgand m2= 4.10 kg are released from rest at a height of h= 4.40 m on a frictionless track. When they meet on the level portion of the track, they undergo a head-on, elastic collision. Determine the maximum heights to which m1 and m2 rise on the curved portion of the track after the collision.

1. Suppose we have two blocks of masses m1 and m2. The block with mass m1 is moving towards block m2 at speed v. After the collision, we measure the total kinetic energy and find that the total kinetic energy after the collision is m2/(m1+m2) less than the kinetic energy before the collision. Find the final speeds of the two blocks. What type of collision is this? 2. Explain, in words, how we know that a freely spinning asteroid in...

Two masses, m1 and m2, are falling but not freely. In addition to gravity, there is also a force F1 applied directly to m1 in the downward direction and a force F2 applied directly to m2 in the horizontal direction. Friction (µs) is present between the two masses and the forces are applied such that they do not rotate. The force F2 is as large as it can be and not have m2 slide relative to m1. (a) Find an...

Suppose that we have two masses, m1 and m2, traveling at initial velocities v1i and v2i . After they collide, they will have velocities v1f and v2f . The collision will happen along a straight line, and there are no external forces involved. Exercise 1 Let m1 = 0.20 kg, m2 = 0.50 kg, v1i = 0.50 m/s, and v2i = 0.0 m/s. If v2f = 0.286 m/s, what is v1f ? For the collision above what are the initial...

Think of a Newtonian cradle made of only two marbles. These two marbles of masses m1 and m2 are each suspended by identical strings. The strings are initially both vertical so the marbles are touching each other when undisturbed. The marble with m1 is shifted away from the initial position until is reaching the height h1 while the length of the string does not change and then is set free to fall and collide with marble m2. What is the...
