Please help me
A San Francisco cable car is pulled by a cable running under the street. The cable moves at a constant speed of 9.50 mi/hr. The person who operates the cable car (called a gripman) operates a grip that grabs hold of the moving cable. (See Figure 2.) The gripman can allow the cable to slide through the grip so that the car can move at a speed that is slower than the cable. In Figure 2 the...
