Akash and Beth are on skateboards. Beth and her skateboard have a combined mass of 62 kg. Akash and his skateboard have a combined mass of 150 kg. Beth pushes Akash to the left with a force of 120N. Assume no friction. What are the accelerations of Beth (+ skateboard) and Akash (+ skateboard)?
One end of a rope is tied to a 11 kg hanging weight. The rope goes over a pulley and the
other end is tied to a 11.7 kg block on flat ground and pulls the block horizontally towards
the pulley. The coefficient of kinetic friction is .2. The block is sliding away from the pulley at
3.0 m/s (the weight is being pulled upwards). What is the magnitude of the acceleration of
the block in meters per second squared?
A railway engine pulls a wagon of mass 10000 kg along a straight track at a steady speed. The pull force in the couplings between the engine and wagon is 1000 N. If the pull force is increased to 1200 N and the resistance to movement of the wagon remains constant, what would be the acceleration of the wagon?
