A model airplane of mass
0.740 kg flies with a speed of 35.0 m/s in a horizontal circle at the end of a 56.0-m-long
control wire as shown in Figure 1(a). The forces exerted on the airplane are sh

Two clowns arrange for a performance with one shooting an apple from anothers head. The
speed of the 125-g arrow just before it strikes the apple is 25.0 m/s, and at the time of impact
it is trave
