Q1 An object with a mass 100 kg decrease in kinetic energy of 500 ki and an increase in potential energy of 1500 kJ. The initial velocity and elevation of the object, each relative to the surface of the earth, are 40 m/s and 30 m, respectively. Determine (a) the final velocity, in m/s. (b) the final elevation, in m
QUESTION 8 Consider the four possible paths of a body moving through gravity as diagrammed below. Which of the following statements is true? Projectile A a. The work done by gravity is greatest for path B. b. The work done by gravity is greatest for path C. c. The work done by gravity is greatest for path D. d. The work done by gravity is the same for all four paths. e. The work done by gravity is greatest for path A.
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

A small block, with a mass of 4 kg, starts from rest at the top of the apparatus shown above. It then slides without friction down the incline, across the first level section, around the loop and then onto the final level section on the right. It then collides with a spring and compresses it, which momentarily brings the block to a stop. The maximum height of the incline is 5 m, the radius of the loop is 1.0 m and the spring constant is 120 N/m.

3) The meaning of the word "WORK" is quite different in physics from its everyday usage. Give an example of an action a person could do that "feels like work" but that does not involve any work as we've defined in this chapter. Support your reasoning with equations/data.
