13. A 10.0-g bullet is fired into a stationary block of wood (m = 5.00 kg) at the speed of 300 m/s, the relative motion of the bullet stops inside the block. Determine the speed of the bullet-plus-wood combination immediately after the collision.

A 10.0-g bullet is fired into, and embeds itself in, a 1.85-kg block attached to a spring with a force constant of 22.4 N/m and whose mass is negligible. How far is the spring compressed if the bullet has a speed of 300 m/s just before it strikes the block and the block slides on a frictionless surface? Note: You must use conservation of momentum in this problem because of the inelastic collision between the bullet and block. (No Response)...

A bullet with mass m(lowercase m) is fired into a block of wood with mass M(uppercase M), suspended like a pendulum, and makes a completely inelastic collision with it. After the impact of the bullet, the block swings up to a maximum height h. Given the values of h = 5.00 cm = 0.0500 m, m = 6.75 g = 0.00675 kg, and M = 2.50 kg, (a) What is the (initial) velocity v_x of the bullet in m/s? (b)...
