A cart of mass Mc is being pulled by an object of mass Mw. Assume Friction is negligible.
a) How many forces are acting on the cart?
b) Two of the forces above cancel each other. which are these forces? How do you know these two forces will add to be zero?
c) What are the forces acting on the mass Mw?
d) If the tension in the string is T, what is the total force Fc acting on the cart parallel to the direction of motion, and what is the total force Fw acting on the hanging object parallel to the direction of its motion?
e) derive how the acceleration a of the cart depends on the mass of the cart Mc, on the mass of the object Mw, and on the acceleration due to gravity g.
