V As shown below, a bullet of mass m and speed v is fired at an initially stationary pendulum bob. The bullet goes through the bob, and exits with a speed of The pendulum bob is attached to a 5 rigid pole of length L and negligible mass. What is the minimum value of v such that the pendulum bob will barely swing through a complete vertical circle? (Use the following as necessary: m, L, g, and M for the mass of the bob.) V = m v/5
A 5.00-g bullet moving with an initial speed of v₁ = 390 m/s is fired into and passes through a 1.00-kg block as shown in the figure below. The block, initially at rest on a frictionless, horizontal surface, is connected to a spring with force constant 920 N/m. The block moves d = 4.40 cm to the right after impact before being brought to rest by the spring. (a) Find the speed at which the bullet emerges from the block. m/s (b) Find the amount of initial kinetic energy of the bullet that is converted into internal energy in bullet-block system during the collision.
