Answer:
Option 5. 1 and 3
Solution:
The only forces acting on the tennis ball after it has left contact with the racquet and the instant before it touches the ground are the force of gravity in the downward direction and the force by the air exerted on the ball.
The ball after it left follows the path of trajectory and as it moves forward in the horizontal direction the force of the air acts on it.
In the whole projectile motion of the ball, the acceleration due to gravity acts on the ball thus the force of gravity acts on the ball in the downward direction before it hits the ground.
False, applied force is when a person or an object pushes on another object
Answer:
The final graph
Explanation:
The graph that curves downwards is negative acceleration. While the position decreases the slop increases.
I think it’s speed will increase, if I understood it correctly
