1. calculate the component of the force that is acting horizontally on the crate
2. state the effect the force has on the line connnecting the crate to the motor
3. each crate has the mass of 200kg calculate the acceleration experienced by each crate
4. the distance covered by each crate is 20m. assuming that each crate starts at rest calulate the speed of each crate at the end of the 20m journey
5. calculate the kinetic energy of the crate at the end of the journey
6.calculate the duration of the journey
7. calulate the work done on the crate during the journey
8.calulate the change in momentum of each crate
9. when the crate reaches the end of its journey it collides with the foam barrier. this barrier brings the crate to rest in a time of 0.1s. calulate the average force acting on the crate during this time.
