Question

A stone is thrown in a vertically upward direction with a velocity of 5m/s. If the acceleration of the stone during its motion is 10m/s2 in the downward direction. What will be the height attained by the stone and how much time will it take to reach there?

Answer 1

given:

u-5m/s

v-0m/s

g-10m/s2

h-?

t-?

v=u+gt

0=5+10t

-5/-10=t

2=t

2second -time

h=ut+1/2gt2

h=5*2+1/2*10*4

h=10+20

h=30
