A tennis player manages to hit a tennis ball with her racquet so that the ball passes over the net and lands in her opponent's court. A very strong wind is present.
Consider the following forces: A downward force of gravity, a force by the "hit", and a force exerted by the air
Which of these forces is (are) acting on the tennis ball after it has left contact with the racquet and before it touches the ground?
a) 1 only b) 1 and 2 c) 2 and 3 d) 1 and 3 e) 1, 2 and 3

Respuesta :

Answer:

d) 1 and 3

Explanation:

When the ball leaves contact with the racquet , the force exerted by the racquet is no longer there . But the gravitational downward force and resistance force exerted by air will be present there . Hence except the force by the "hit" , all forces will be present there .

Hence option ( d ) is correct .
