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)

Your pendulum clock which advances 1.0 s for every complete oscillation of the pendulum is running perfectly on earth at a site where the magnitude of the acceleration due to gravity is 9.80 m/s2. you send the clock to a location on the moon where the magnitude of the acceleration due to gravity is 1.65 m/s2.

Is it possible to use the energy from two atoms colliding to create a clean burning lasting fuel source with a large amount of force? is it also possible to harness that energy from the two atoms colliding to create a clean energy source that will last for years from just two atoms colliding. is there a possibility to control and store that energy for years but slowly let the energy out enough to power cities cheaper and faster.
