Question

A bullet with mass m₁ is fired horizontally at a velocity v₁

If the bullet strikes a block of mass m₂ at horizontal distance s₁,

(a) how far h has it dropped?

Assuming the bullet’s horizontal speed remains constant,

(b) what will be its resultant speed v_R as it hits the block?

(c) At what angle Θ below the horizontal does it strike the block?

The bullet remains in the block, which slides down a long ramp, which

sits at the same angle to the horizontal as the impact of the bullet.

(d) At what initial speed v₂ will the block slide?

(e) The block slides to a stop on the ramp. If the ramp-block system has a coefficient of friction of µ, what will be the displacement s₂ of the block?

(f) How much heat Q₁ is generated by the impact of the bullet on the block?

(g) How much heat Q₂ is generated by the friction of the block on the ramp?

this is all the instructor gave us. No diagrams, pictures, etc. Fun isn't it? ;)
