Q1. A driver in a car travelling at the speed of 78 km/h sees a cat km away on the road. How long will it take for the car to accelerate uniformly to a stop in exactly 99 m?

Q2. A crate of mass 12.50 kg is pulled up a rough incline with an initial speed of 1.50 m/s. The pulling force is 100N parallel to the incline, which makes an angle of 17° with the horizontal. The coefficient of kinetic friction is 0.40, and crate is pulled 5.85 m.
