Question

A stone is thrown vertically upward with a velocity of 25 m/s. How long does it take to reach the maximum height? also, calculate the height.

Answer 1

Answer:

Approximately 32 it is the correct answer

Answer 2

Answer:

v^2 -u^2 = 2gs

here v = 0 m/s

u= 25m/s

g = -10m/s^2

putting these value in equation,

0^2 - 25^2 = 2× (-10)×s

0 - 225 = -20s

-225 = -20s

s = -225/-20

s = 11.25m

height = 11.25 m

Now, v= u + at

0 = 25 + (-10)t

-10t = -25

t = 2.5second
