Question

A stone is thrown in a vertically upward direction with a velocity of 5ms 1.If the acceleration of the stone during its motion is 10ms 2 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

A=5m/s
A=10m/s2
v=u+at
5=0+10*t
5-0/10=t
5/10=t
1/2=t
t=0.5s
v=h/t
h=v*t
h=5*0.5
h=2.5m
