Q1. The driver of a 1700 car travelling on a horizontal road at 140 suddenly applies brakes. Due to the slippery pavement, friction of the road on the tires of the car, which is what slows down the car, is 23.0 of the weight of car.

What is the acceleration of car?

How many meters does it travel before stopping in the conditions?

Q2. Boat A negotiates a curve whose radius is 370 m. Boat B negotiates a curve whose radius is 120 m. Each boat experiences the similar centripetal acceleration. What is the ratio of speed of boat A to that of boat B?
