Answer:
6 seconds
Explanation:
If it took the ball 3 seconds to reach the maximum height, then it also took 3 seconds to return to its original height. So it was in the air for a total of 6 seconds.
The time for the ball to be in the air will be 6 seconds.
The period is found as the ratio of the displacement and the velocity. Its unit is the second and is denoted by t.
The value of time needed to complete the upward and the downward motion is the total period. T is the time at which the ball first hits the ground.
The given data in the problem is;
The time required to move upwards is,t₁ = 3 sec
The time required to move downwards is,t₂ = 3 sec
The total period is the sum of the time required to move upwards and the time required to move downwards.
T =t₁+t₂
T =3 +3 sec
T=6sec
Hence the time for the ball to be in the air will be 6 seconds.
