Calculation of force of interaction

Please help me solve this problem: two hydrophobic glass slides measuring 1 cm x 1 cm x 1 mm are floating on water with their sides parallel to each other. Estimate the force of interaction between the solids as a function of their separation distance. Assume that the intrinsic contact angle of the water is 110 degrees. Wha ...continues

Impulse

A 50 kg cart is moving across a frictionless floor at 2 m/s. A 70 kg boy, riding the cart, jumps off so that he hits the floor with zero velocity. What impulse did the boy give to the cart? What was teh velocity of hte cart after the boy jumped?
