Question1
The driver of an 1800{rm kg} car travelling on a horizontal road at 114{rm km}/ {rm h} suddenly applies the brakes. Because of a slippery pavement, the friction of the road on the tires of the car, which is what slows down car, is 23.0 percent of the weight of the car.
What is acceleration of the car?
How various meters does it travel before stopping under these conditions?
Question2
A car travels due east with a speed of 49.0 km/h. Raindrops are falling at a constant speed vertically with respect to Earth. The traces of the rain on the side windows of a car make an angle of 53.0° with vertical. Find out the velocity of the rain with respect to the reference frames.
