Question

An egg falls off a table. The floor is 0.8 m from the table top.
a) Calculate the time taken to reach the ground.

b) Calculate the velocity of impact with the ground.​

Answer 1

Explanation:

u=0, h=0.8m, t=?, g=9.8m/s², v=?

finding b first,

v²-u²=2gh

v²=2×9.8×0.8

v=√15.68

v=3.959 m/s.

finding a now,

v=u+at

3.959-0=9.8t

3.959/9.8=t

0.40s=t

hope this helps you.
