Question

2. Suppose an object at a given location has potential energy of U, = 10 J and kinetic energy of K,-20 J. Assuming there are no other outside forces acting on the object, how much kinetic energy does the object have when it's potential energy is Ur 5 (a) K,= 5 J (b) K 20 J (c) Kr = 35 J (d) This situation cannot be achieved. 3. Suppose an object at a given location has potential energy of U 10 J and kinetic energy of K-20 J. Assuming there are no other outside forces acting on the object, how much kinetic energy does the object have when it's potential energy is U = 40 J. (a) K,=-10 J (b) Kf= 20 J (c) Kf= 50 J (d) This situation cannot be achieved. 4. Suppose an object at a given location has potential energy of U, 10 J and kinetic 20 J. Assuming there are no other outside forces acting on the object, 15 J. energy of K how mach potential energy does the object have when it's kinetic energy is K, (a) Uf= 5 J (b) Uf= 10 J (c) U-15 J (d) This situation cannot be achieved. 5. Suppose an object at a given location has potential energy of U, 10 J and kinetic energy of Ki 20 J. Assuming there are no other outside forces acting on the object, how much potential energy does the object have when it's kinetic energy is Kf = 40 J (a) U,=-10 J (b) U, = 10 J (c) Uf= 40 J (d) This situation cannot be achieved. 6. Suppose an object of mass m 4kg is at rest at a given location with potential energy of Ui 50 J. Assuming there are no other outside forces acting on the object, how fast does the object move when it reaches potential energy of U 0J? (a) u,=0 m/s (b) uf= 5 m/s (c) v/ = 10 m./s (d) u,= 25 m/s
