A body thrown vertically up with initial velocity 52 m/s from the ground  passes twice a point at h height above at an interval of 10 s . Find the height h where g is given to be 10 m/s square .

Expert Answer:

Given that the body is thrown up with initial velocity , u = 52 m/s
it passes twice a point of height h in t= 10 sec.
Therefore :
Syntax error from line 1 column 49 to line 1 column 73. Unexpected '<mstyle '.
As it passes twice a point of height H , we can write S =2 h = 20 m
2 h = 20 m
h = 10 m
The height h= 10 m
