Q.1) A 5.8-g bullet travelling at 440 m/s strikes a large wooden fence post. If an average force required to stop the bullet was 4.5 x 10^3 N, how far into the fence post did the bullet penetrate?

2) You work for a moving company and are given the job of moving two crates (masses are 130kg and 280kg) held together by a rope attached between the two. You pull on a rope attached to the larger crate giving the system the acceleration of 0.29m/s2. What is the tension in each rope?
