Despite a very strong wind, a tennis player manages to hit a tennis ball with her racquet so that the ball passes over the net and lands in her opponents court. Consider the following forces: 1 - A downward force of gravity. 2 - A force by the "hit".

A train has a length of 102 m and starts from rest with a constant acceleration at time t = 0 s. At this instant, a car just reaches the end of the train. The car is moving with a constant velocity. At a time t = 18.

To set a speed record in a measured (straight-line) distance d, a race car must be driven first in one direction (in time 11) and then in the opposite direction (in tim e t). (a) To eliminate the effects of the wind and obtain the car's speed v.
