I need help with this physics question. It relates to work/kinetic/potential energy. Approximations for average weight of a human can be used.
Truck brakes can fail if they get too hot. In some mountainous areas, ramps of loose gravel are constructed to stop runaway trucks that have lost their brakes. The combination of a slight upward slope and a large coefficient of rolling friction as the truck tires sink into the gravel brings the truck safely to a halt. Suppose a gravel ramp slopes upward at 6.0 ° and the coefficient of rolling friction is 0.35. Part A Use work and energy to find the length of a ramp that will stop a 15,000 kg truck that enters the ramp at 38 m/s. Express your answer to two significant figures and include the appropriate units. 1 = µA Value m ?
A 50-g mass on the end of a spring at its equilibrium position is stretched a distance of 5.00 cm and held there by a force of 10.0 N and then suddenly let go. Assume no friction.

Which of the following statements are true? O If you apply a force to a moving object, you are doing work on that object. O It is possible to feel exertion without doing work on anything. O You feel exertion only when you do work on external objects. O None of the other statements are true. If a machine is more powerful, it can do work for longer amounts of time. O If you want to keep a heavy object from falling. work must be done on it to accomplish that goal.

Three different objects, all with different masses, are initially at rest at the bottom of a set of steps. Each step is of uniform height d. The mass of each object is a multiple of the base mass m: object 1 has mass 4.90m, object 2 has mass 1.46m, and object 3 has mass m. When the objects are at the bottom of the steps, define the total gravitational potential energy of the three-object system to be zero. If the objects are then relocated as shown, what is the new total potential energy of the system? Each answer requires the numerical coefficient to an algebraic 2 expression. Each algebraic expression is given using some 3 combination of the variables m, g, and d, where g is the acceleration due to gravity. Enter only the numerical coefficient. (Example: If the answer is 1.23mgd, just enter 1.23) U g,system mgd
