A student m1 = 66 kilogram stands on a long cart m2 = 122 kilogram initially at rest. He begins to run in the cart with a speed relative to the ground of v1 = 3.1 meter per second.
Part (a) Write an expression for the carts velocity relative to the ground while the student is running. Suppose the student is running in the positive x-direction.
Part (b) Determine the velocity in meters per second?
Part (c) Find the student velocity relative to the cart in meters per second?
