A:
A particle of m1=0.30 kg slides along the right axis on a frictionless floor with a speed of 2.0 m/s. When it reaches x = 0, it undergoes a one-dimensional elastic collision with stationary particle 2 of mass m2=0.40 kg. When particle 2 then reaches a wall at xw = 72 cm, it bounces from the wall with no loss of speed. At what position on the x axis (in cm) does particle 2 collide with particle 1?

- A steel ball of mass 0.850 kg is fastened to a cord that is 65.0 cm long and fixed at the far end. The ball is then released when the cord is horizontal, as shown in the figure. At the bottom of its path, the ball strikes a 3.30 kg steel block initially at rest on a frictionless surface. The collision is elastic. Find (a) the speed of the ball and (b) the speed of the block, both just after the collision. (a) Number (b) Numbe i i Unit UnitA woodblock of mass Mw = 200 g is projected from the ground at a speed v0 = 35 m/s and at an angle, θ0 = 50º. When at height h = 24 m the woodblock was hit by a bullet of mass Mb = 25 g which was moving at vb = 220 m/s and at an angle θb = 70º. After the collision, the bullet embedded itself in the block and move together and land at point A on the ground. Then they move on the ground that has a coefficient of kinetic friction µk = 0.5 and starts to compress a horizontal spring at point B. The distance between point A and B is 18 m and the spring constant k = 3×10^2 N/m. The right end of the spring is fixed, and all motions are confined in x-y plane. (a) Was the collision between the wood block and the bullet elastic or inelastic? Explain quantitively. (b) Find the maximum height from the ground the block with the bullet reached. (c) How far is point A from the launch point of the woodblock? (d) Calculate the velocity at which the block-bullet system lands at point A. What…A 0.0101-kg bullet is fired straight up at a falling wooden block that has a mass of 4.08 kg. The bullet has a speed of 575 m/s when it strikes the block. The block originally was dropped from rest from the top of a building and had been falling for a time t when the colllision with the bullet occurs. As a result of the collision, the block (with the bullet in it) reverses direction, rises, and comes to momentary halt at the top of the building. Find the time t.
