Question

An object is dropped for reset from the top of a 100 m building . how long will it take for the object to hit the ground

Answer 1

Answer:

if we use gravity that is 9.8m/s then we get the answer 4.42 seconds

Explanation:

lets do it steps by steps, s=u/t +1/2 at square

100=0+1/2×9.8 time square

100=4.9 time square

100/4.9= time square

t= 10×2.21. as sides changed the signs also changed

t=4.42
