Someone always park a car on an inclined plane drive way. On snow, when she parked the car, the car start rolling because there is very small force of friction between the tire the snow. In this problem, please neglect any force of friction between the tire and the snow. Suppose the ramp makes an angle of 0 = 20.0 degree. (a) Determine the acceleration of the car (b) If the length of the incline plane is 25.0 m and the car starts from rest at the top, how long does it take to travel to the bottom? (c) What is the car's speed at the bottom?

Question
Someone always parks a car on an inclined plane driveway. On snow, when she parked the car, it starts rolling because there is a very small force of friction between the tire and the snow. In this problem, please neglect any force of friction between the tire and the snow. Suppose the ramp makes an angle of θ = 20.0 degrees.

(a) Determine the acceleration of the car.

(b) If the length of the incline plane is 25.0 m and the car starts from rest at the top, how long does it take to travel to the bottom?

(c) What is the car's speed at the bottom?
