Acoin released at rest from the top of a tower hits the ground after falling 1.5 s. what is the speed of the coin as it hits the ground?

The speed of coin as it hits the ground is 14.7 m/s.

Given data:

Initial speed of coin is, .

Time taken to fall on ground is, .

Use first kinematic equation of motion as,

here, g is the gravitational acceleration.

Solving as,

Thus, the speed of coin as it hits the ground is 14.7 m/s.

initially coin is at rest and then it drop for total time t = 1.5 s

so here the speed of the coin at which it will hit the floor is to be find

here we know that

a = 9.8 m/s^2

t = 1.5 s

now from above equation

so it will hit the floor with speed 14.7 m/s

what was the answer?

do you have a formula possibly
