Let's consider an elastic collision between two marbles, where the marbles are confined to one dimension. Suppose marble 1 with a mass of 40 g is shot with a speed of 5 m/s into marble 2 with a mass of 20 g. What will be the speed of marble 2 after the collision?
A particle moves in an elliptical path given by the equation r = bcos(omega)ti + 2bsin(omega)tj . Discover the angle between the acceleration vector and the velocity vector at time t = p/(4(omega)).
