Suppose there is a stack of ten books on the floor. Each book has a mass of 1.40 kg. (a) Determine the force that the eighth book exerts on the ninth book. (count up from the bottom) (b) Determine the force Suppose there is a stack of ten books on the floor. Each book has a mass of 1.40 kg. (a) Determine the force that the eighth book exerts on the ninth book. (count up from the bottom) (b) Determine the force that the second book exerts on the first. (c) Find the normal force the first book exerts on the floor if a boy with mass 60.0 kg jumps off the top of the stack with an acceleration of 3.00 m/s2, upward.
A man of mass 95.00 kg is hanging from the end of a rope of mass 2.50 kg. The other end of the rope is attached to a helicopter. If the helicopter rises such that the man accelerates upward at 4.000 m/s2 find the tension in the rope at its: (a) bottom, (b) middle, and (c) top. the second book exerts on the first. (c) Find the normal force the first book exerts on the floor if a boy with mass 60.0 kg jumps off the top of the stack with an acceleration of 3.00 m/s2, upward.
