A 12.5 kg box, which is on the top of a horizontal, frictionless table, is connected to a second 7.75 kg box, which is hanging off of the table by an inextensible, massless cord that runs over a massless, frictionless pulley. What is the magnitude of the acceleration of the two boxes and the magnitude of the tension in the cord? Include a force (or free-body) diagram of the situation.

A 12.0 kg block A which hangs from a string that passes over a pulley and is connected at its end to a 30.0 kg block B which rests on a frictionless table. Find the acceleration of the two blocks under the assumption that the string is massless and the pulley is masless and frictionless. What is the ttension on the string?

A contestant in a winter sports contest pulls a 41 kg block of ice in the positive horizontal direction with a rope over his shoulders over a frozen lake as shown in the figure. Assume the coefficients of static and kinetic friction are us=0.1 and uk=0.03.  Calculate the minimum force F he must exert to get the block sliding in newtons.  What is ths acceleration in m/s2  once it starts to move, if that force is maintained?

You want to push your 53.0 kg friend up the 33.0° ramp of a slide in a nearby park. You do so bypushing your friend with a 510.0 N horizontal force. The coefficient of kinetic friction betweenyour friend and the slide is 0.170. Find the acceleration of your friend up the slide. What is thenormal force from the ramp on your friend?
