Use the worked example above to help you solve this problem. A car of mass m is on an icy driveway inclined at an angle θ = 21.0°, as shown in the figure.
(a) Determine the acceleration of the car, assuming the incline is frictionless. m/s2
(b) If the length of the driveway is 23.5 m and the car starts from rest at the top, how long does it take to travel to the bottom? s
(c) What is the car's speed at the bottom? m/s
