A 10kg object moves from a position (x,y, :) = (1.0, 2.5, 1.5) to (2.5, 1.5, 2.0) when a force F = 3x"i 7 6352 j + 7 kn acts on the object. All values are given in SI units. What is the work done by the force F on this object? A block slides down an incline plane with 'iction. Identify all the forces on the block and determine whether the work done by each force on the block is positive, negative, or zero. If the block is moving at a constant speed, what is the total work done on the block? If the block in the previous problem has a mass of 1.0 kg, the ramp is at an angle of 25, and the block slides down the ramp for a distance of 1.5 m calculate the work done by each force. A 4500 kg truck moving 24 m/s is brought to rest in a horizontal \"runaway truck ramp\" over a distance of 75 meters. What was the average frictional force that stopped the truck? A roller coaster is moving along a \"frictionless\" track at a speed of 20 m/s. After rising up a 10 meter hill, what is the speed of the roller coaster? The potential energy of an object is given by the equation U: 3x2 + 2.76 +5. What is the conservative force that leads to this potential energy
