Two men A and B, each having a weight of 160lb stand on a200lb cart. Each runs with a speed of 3ft/s measured relativeto the cart. Determine the final speed of the cart if:
a) A runs and jumps off, then B runs and jumps off the sameend
b) both run at the same time and jump off at the sametime.
Neglect the mass of the wheels and assume the jumps are madehorizontally.
