Question

2.
A 20-g bullet is travelling at 400 m/s when it becomes embedded in a 3-kg stationary block.
The coefficient of kinetic friction between the block and ground is 0.2 Use the principle of linear
momentum and impulse to determine the velocity of system immediately after the bullet becomes
embedded. Then, use the work-energy theorem to determine the distance that the block will slide
before it stops. The frictional force between the block and surface can be neglected during the initial
impact but cannot be neglected when analyzing the sliding distance of the block.

A car A is stuck on the railroad tracks as a train B approaches with a speed of 120 km/hr. As soon as the problem is detected, the train's emergency brakes are activated, locking the wheels and causing the train's wheels to slide relative to the tracks. If the co-efficient of kinetic friction between the wheels and the track is 0.2, use work energy principle to determine the minimum distance d at which the brakes must be applied to avoid a collision under the following circumstances. Mass of the train is 195,000 kg. A B d
