Problem Statement | A ball can be rolled down one of four different ramps, as shown in the diagram. The nal elevation loss of each of the ramps is the same. Neglecting friction, for which ramp will the speed of the ball be the highest at the bottom? (a) The speed of the ball will be the same for all ramps. (b) Rampx (c) RampY (d) RampZ Problem Statement | Two sleds (A and B), connected by a rope with tension T, are pulled at a constant speed by a force F, as shown in the gure. Which of the following statements are true? (a) The work done by T on sled A is half the work F does on B. (bi The work from friction on B is twice the work from friction on A. (c} The change in energy of the A+B system is zero. (d) The net impulse exerted on A is less than on B. y'o'o;+oy.+'_op;s (e) The net impulses exerted on both A and B are zero. A (f) Both A and B experience positive net external work. (g) Both A and B experience negative net external work. (hi Both A and B experience zero net external work. Problem Statement | The gure shows several plots, one of which labeled as representing the position ofa mass on a fric- tionless surface, connected to a horizontal spring that is oscillating back and forth. The other two plots are numbered | and II. Which of the following statements are true regarding these plots and this situation? (a) Plot I could represent the mass's velocity as a function of time. (b) Plot I could represent the mass's acceleration as a function of time. (c) Plot M could represent the mass's acceleration as a function of time. (d) The mass has the greatest amount of potential energy at points A, C, and E. (e) The mass has the greatest amount of kinetic energy at points A, C, and E. (f) The potential energy of the mass is maxi- mum when its magnitude of acceleration is greatest. (g) The kinetic energy of the mass is greatest when its position is zero
