Question

If you jump off a 10 m diving platform, how long will it take you to hit the water?

A. 1.43 s
B. 1.74 s
C. 2.04 s
D. 1.97 s

Answer 1

t=1.43 s

Option A is the correct option.

Solution,

S=10 m

u=0 m/s

a=9.8 m/s^2

Now,

`2s = a {t}^(2) \\ or \: {t}^(2) = (2 * 10)/(9.8) \\ or \: {t}^(2) = (20)/(9.8) \\ or \: {t}^(2) = 2.04 \\ or \: t = √(2.04) \\ t = 1.43 \: seconds`

hope this helps...

Good luck on your assignment...
