Answer:
0.82 m
Explanation:
The ball is in free fall - uniform accelerated motion with constant acceleration downward, (acceleration of gravity). So we can use the following suvat equation to solve the problem:
where
v is the final velocity
u = 4 m/s is the initial velocity
a is the acceleration
s is the displacement
At the maximum displacement, v = 0 (the velocity becomes zero). Substituting and solving for s, we find:
Answer:
Explanation:
Given that:
- force applied,
- displacement,
(length of a tennis court)
- time taken for pushing, t = 40 s
Since, work is given by:
Now, power is given as:
