Q1. A 3.72 g bullet moving at 290 m/s enters and stops in an initially stationary 3.30 kg wooden block on a horizontal frictionless surface.

What's the speed of the bullet block combination?

What fraction of the bullet's kinetic energy was lost in this perfectly inelastic collision?

How much work was done in stopping bullet?

If the bullet penetrated 5.00 cm into the wood, what was the average stopping force?

Q2. A super tanker with the mass of 3.36 × 109 kg is moving with a constant velocity. Its engines generate a forward thrust of 4.11 × 105 N. Determine (a) magnitude of the resistive force exerted on the tanker by the water and (b) magnitude of the upward buoyant force exerted on the tanker by the water.
