We have the equation of motion , where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.
Here displacement = 135 m, Initial velocity = 0 m/s, acceleration = 9.81
Substituting
A box falls out of a stationary helicopter hovering 135 m above the ground will take 5.25 seconds to reach the ground.
Answer:
The value is
Explanation:
From the question we are told that
The landing speed is
The distance traveled is
The velocity it is reduced to is
Generally the average acceleration is mathematically represented as
=>
