asked • 08/11/21Calculation work
A block is sitting on a flat table is held in place and is connected to a vertically hanging ball via a taught massless rope laid over a frictionless pulley of negligible mass. The weight of the block is 5.9 N and the weight of the ball is 17.0 N. The coefficient of kinetic friction for the table is 0.194. The block and ball system is initially at rest until the block is allowed to move.
What is the net acceleration of the system?
What is the work done by the force of friction after the ball falls 10 cm?
What is the work done by the normal force on the block at that point?
What is the total kinetic energy of the system at that point?
