A cart of mass M1 = 6 kg is attached to a block of mass M2 = 3 kg by a string that passes over a frictionless pulley. The system is initially at rest and the table is frictionless. After the block has fallen a distance h = 1 m, What is the work Ws done on the cart by the string?
heres how it looks...
The Attempt at a Solution
I know work is F * distance moved, and i can surmise that M1 moves the same distance as M2 (1m) cause theyre contrained by the string.
I know that force on M2 is 3 * 9.8 = 29.4N,
No friction so force on M1 (pulling horizontally) is also 29.4N
distance is 1 meter, so 29.4N * 1m = 29.4J
