#5. A girl pushes a crate along the floor with an applied force of 150 N. If the frictional forces add up to 125 N and the crate has a mass of 50 Kg. What acceleration does the crate obtain? [1-2] #6. A diver falls vertically from a height of 10m. She hits the water and comes to rest underwater 3.0m from the surface. If she has a mass of 55kg, calculate the force that the water exerts on her as she comes to rest. [1-3] #7. Find the acceleration and Tension for the following pulley-mass system. Given mass is 5 kg and mass b is 7 kg. Assume zero friction. Show all work. [1-3] pulley string B
