Physics: Speed of car at bottom of driveway; initial speed of bullet
20 A 2.10 x 10³ kg car starts from rest at the top of a 5.0 m long driveway that is sloped at 20° with the horizontal. If an average friction force of 4.0 x 10³ N impedes the motion, find the speed of the car at the bottom of the driveway.

An 8.00 g bullet is fired into a 2.5 kg block that is initially at rest at the edge of a 1.0 m high table. The bullet remains in the block, and after impact the block lands 2.00 m from the bottom of the table. Determine the initial speed of the bullet.
