A) What is the expected value of acceleration of a car (in m/s2) on a frictionless track that is inclined at an angle of 9⁰. B) At an angle of incline of the track at 6⁰, in how much time is the cart expected to travel 1 meter, if it starts from rest?
C) If a car starts rolling down a road inclined at 10 how far (in meters) would it go in 2.3 minutes. (ignore friction)
