Are you asking us what we think of the universe? lol
Answer:
The time taken for the ball to return to the starting point is is 7.4 s
Explanation:
Given;
initial velocity of the ball, u = 36 m/s
the final vellocity at maximum height, v = 0
let time taken for the ball to reach maxmimum height = t
Time taken for the ball to return to the starting point is known as time of flight, calculated as;

T = (2 x 36) / 9.8
T = 7.4 s
Therefore, the time taken for the ball to return to the starting point is is 7.4 s
Answer: Newton
Explanation:
Force is measured in Newtons, which are units that equal 1 kg * m/sec2. You can calculate the amount of force that an object experiences with the equation force = mass * acceleration
Your answer would be 4.0 hz.
