A 2.00-kg object hangs, at rest, on a 1.00-m-long string attached to the ceiling. A 100-g mass is fired with a speed of 20 m/s at the 2.00-kg mass, and the 100.00-g mass collides perfectly elastically with the 2.00-kg mass. Write an equation for the motion of the hanging mass after the collision. Assume air resistance is negligible.
George of the Jungle, with mass m, swings on a light vine hanging from a stationary tree branch. A second vine of equal length hangs from the same point, and a gorilla of larger mass M swings in the opposite direction on it. Both vines are horizontal when the primates start from rest at the same moment. George and the gorilla meet at the lowest point of their swings. Each is afraid that one vine will break, so they grab each other and hang on. They swing upward together, reaching a point where the vines make an angle of 35.0 with the vertical. Find the value of the ratio m/M.
PLEASE WRITE DONT TYPE A Ballistic Pendulum. A 12.0-g bullet is fired with a speed of 380 m/s into a ballistic pendulum with mass 6.0-kg , suspended from a cord 70.0 cm long.

(c)Compute the kinetic energy of the bullet and pendulum immediately after the bullet becomes embedded in the pendulum.
A rifle bullet with mass 8.00 gg strikes and embeds itself in a block with mass 0.992 kgkg that rests on a frictionless, horizontal surface and is attached to an ideal spring. The impact compresses the spring 15.0 cm.

A 5.00 gram bullet into a 1.00 kg block attached to a spring [k=900 N/m]. The bullet emerges through the block on the other side. If the block moves 5.00 cm to the right before it stops, what is the final velocity of the bullet?
A 0.0421 kg bullet is five horizontally into a 2.77 kg wooden block attached to one end of a mass list, horizontal spring (k=897 N/m). The other end of the spring is fixed in place, in the spring is unrestrained initially. The block rest on a horizontal, frictionless surface. The bullet strikes to block perpendicularly and quickly comes to a halt within it. As a result of this completely inelastic collision, the spring is compressed along its axis and causes the block/bullet to oscill with an amplitude of 0.180 m. What is the speed of the bullet?
