A wood block 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 wood block was hit by a bullet of mass mb = 25 g which was moving at vb = 220 m/s and at an angle θb = 70º.

A wood block 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 wood block 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 coefficient of kinetic friction μk = 0.5 and start to compress a horizontal spring at point B. The distance between point A and B is 18 m and the spring constant k = 3×102 N/m. 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 wood block?
Figure 2 shows a ballistic pendulum consists of 5 kg slender rod and 10 kg solid cylinder. The pendulum is originally at rest, θ = 0ᵒ. A 10 g bullet with velocity v is fired to the solid cylinder. c) However, it is observed that the cylinder swing upward to a maximum angle of θ = 22ᵒ. Determine the actual initial value of v. Then, analyze the linear impulse imparted by the bullet on the cylinder. Also, evaluate the force on the rod immediately just after theimpact.
Same situation as before. This time it s a block of mass 1.21 kg sliding with a constant velocity of 3.27 m/s to the north, which collides 100% elastically with a second, stationary block, of mass 4.57 kg, head-on, and rebounds back to the south, eventually colliding 100% elastically with a wall and rebounding northward. It then overtakes the second block, which is still moving north as a result of the first collision. What will be the speeds of the 1.21-kg and 4.57-kg blocks, respectively, after their SECOND collision with one another? 2.53 m/s and 1.62 m/s 4.22 m/s and 5.39 m/s 1.73 m/s and 0.36 m/s 2.40 m/s and 2.88 m/s
A hammer head H having a weight of 0.26 lb is moving downwards at 40 ft/s when it strikes the head of a nail of negligible mass and drives it into a block of wood as shown. Find the impulse on the nail if it is assumed that the grip at A is loose, the handle has a negligible mass, and the hammer stays in contact with the nail while it comes to rest.

A horizontal bar of mass m1 and small diameter is suspended by two wires of length l from a carriage of mass m2 which is free to roll along the horizontal rails. If the bar and carriage are released from rest with the wires making an angle θ with the vertical, determine the velocity vb/c of the bar relative to the carriage and the velocity vc of the carriage at the instant when θ = 0. Neglect all friction and treat the carriage and the bar as particles in the vertical plane of motion. I have Vc but I can not algebraically solve for Vb/c.
