A rock of mass 150g is thrown vertically up into the air with a speed of 15 m/s. How high will it travel?
A ball swings in a vertical circle at the end of a rope 1.40 m long. When the ball is 35.5° past the lowest point on its way up, Determine the magnitude of its radial acceleration
An asteroid is discovered to have a tiny moon that orbits it in a circular path at a distance of 103 km and with a period of 47.0 h. The asteroid is roughly spherical (unusual for such a small body) with a radius of 24.9 km.
