The 25g bullet travelling at 350ms strikes a block of wood., Ask an Expert

Academics

Q. The 25g bullet travelling at 350m/s strikes a block of wood. The block of wood exerts an average force of 50,000N opposing the motion of the bullet. How far does the bullet penetrate while stopping?

Q. A 730{rm kg} car stopped at an intersection is rear-ended by an 1800{rm kg} truck moving with a speed of 15.5m/s.

If the car was in neutral and its brakes were off, so that collision is approximately elastic, find the final speed of the truck.

Find the final speed of car.
