a body is allowed to fall freely , and it reaches the ground with a velocity of 28 m/s calculate the height
shreyaa:
i forgot to complete it
calculate the height from which it was dropped
wait i acn give u answer
a data of time is missing
provide the time to hit the ground.
please provide the time in comment box.
time should be found too only acceleration due to gravity is given (g=10m/s)
only height is asked
now reload and select any best answer
your answer is 39.8m,and u hav to find the time additionally( t =2.85sec)

it can be calculated
free fall so u=0 v=28 m s^-1
h=39.2 m
gt=v
free fall so u=0 v=28 m s^-1
h=39.2 m
gt=v
Thanks for providing me with the time computation

Given :
velocity v = 28 m/s
v= gt
t =v/g
= 28/10
= 2.8 sec
we know h = 1/2( g* (t* t) )
let t = 2.8 sec
h = 1/2 (10 ) ( 2.8 ²)
h = 39.2 m
velocity v = 28 m/s
v= gt
t =v/g
= 28/10
= 2.8 sec
we know h = 1/2( g* (t* t) )
let t = 2.8 sec
h = 1/2 (10 ) ( 2.8 ²)
h = 39.2 m
