(a) The height of the cliff will be 8.26 meters.
(b) The time would it take to reach the ground will be 0.717 sec.
<h3>What is velocity?</h3><h3 />
The change of displacement with respect to time is defined as the velocity. Velocity is a vector quantity. it is a time-based component.
(a) The height of the cliff will be 8.26 meters.
According to Newton's second equation of motion

Hence The height of the cliff will be 8.26 meters.
(b)The time would it take to reach the ground will be 0.717 sec.
We must have the final velocity to find the time so;

According to Newton's third equation of motion ;

Hence the time would it take to reach the ground will be 0.717 sec.

Salt is a substance because a substance is a material that has constant composition regardless of its source. Salt is the only option that matches this description
The speed is constant since there is no opposite force facing the car
That’s my best guest hope it helps !! :)
Steam enters a cylinder—- A
The bowling ball is at rest, so it only has gravitational potential energy.
Ug = mgy
Ug = (2)(9.8)(40) = 784 J
Need any more help?
