Q1. A motorist travelling at 82 km/hr is being chased by a police car at 131 km/hr. If the police car starts from 3.5 km back, how long does it take to catch the motorist? Leave time in hours.

Q2. The combined weight of the crate and dolly is 560.0 N. The man pulls on the rope with a constant force of 24.0 N.

(a) Assume that no friction forces oppose the motion, what is the acceleration of system (crate and dolly)?

(b) Assume same magnitude of force is applied by the man pulling the crate, but that the rope now makes an angle of 15.0o relative to (above) the horizontal. What is the acceleration of crate + dolly in this case?
