Question
Apartile is thrown vertically upwards with a velocity of 19.6 ms-1. The position of the body after 4s will be
Options
A.at the highest point
B.at the mid-point of the line joining the starting piont and the highest point
C.at the starting point
D.none of the above
Solution
Cleary the time taken by the particle to reach the higest point is given by v = u - gt
or, t =
or, t = 2s.
or, t =
or, t = 2s.
So, the particle will reach the initial point in 2t i.e. 4 seconds.
