If a body thrown upwards vertically with velocity u at a point above the ground when the same body passes through a same point during it journey at what time?
Hello student,
We have to recall, all of the basics of physics.
The time taken, in throwing of the body towards point with velocity u is (let t1)= u/g , g equal to gravity.
Time for upward journey at this particular starting point,(= (u/g - t2)
So your answer is 2(u/g - t2)
