HELP found the missing number and what type of decay is the equation
1 Answer
Note that momentum can be related to kinetic energy: KE = p2m. The presence of friction in our experimental setup results in a ratio of (total moment before/total momentum after) the collision to be O a. Less than 1.0 because kinetic energy is lost to friction. O b. More than 1.0 because kinetic energy is gained in the collision due to friction. O c. equal to zero because of energy loss due to friction. O d. None of the above is correct.

65% Wed 11:13 PM MyMassasoit Login a In a downhill ski race, surprisingly, little advantage is gained by getting a running start. (This small hills.) To demonstrate this, find the final speed in m/s and the time taken in seconds for a skier who skies 67.0 m along a 25 slope neglecting friction for the following two cases. (En speeds to at least one decimal place Your s is because the initial kinetic energy is small compared with the gain in gravitational potential energy even on (a) starting from rest final speed the final m/s time takern (b) starting with an initial speed of 3,40 m/s final speed m/s time taken (c) Does the answer surprise you? Discuss why it is still advantageous to get a running start in very competitive events. Reading

A student is tasked with using a force table to balance a small ring in the center of a pin, as shown in Figure 1. For each of the four strings shown, one end is attached to the small ring, and the other end is attached to a hanger that can hold masses. Each string is wrapped around a pulley so that the hanger and masses are at rest. The location of each pulley may be changed. Figure 2 shows a top-down view of the free-body diagram of the forces exerted on the pin at a particular moment in time. From a top-down perspective, in what direction will the pin accelerate? A-Up and to the right B-Up and to the left C-Down and to the right D-Down and to the left
