1) a loaded cart with a mass of 96 kg sits at reat atop a 40 degreeinclined plane that measures 20.5m long. accidentally the cartstarts so to roll down the inclined plane with a frictional forceof 5550N working against it for the intire 20.5m. deteremine thespeed at the bottom og the incline plane.
2) a 1,420kg boulder at rest, begins to roll down a 52m longhillside. while rolling, the ground causes a frictional force of12,040N. the boulder arrives at the bottom of the hillside with aspeed of 19.5m/s. determine the boulder's original height.
3)a 2,420kg car starts from rest at the top of a 7.2m long drivewaysloped at a 25 degree angle to the horizon. if a fractional forceof 4,200N retards the motion, find the speed of the cat at thebottom of the driveway.
