MCQ Solution: Kinematics
An object is projected up wards with velocity of 100 m/sec. it will strike the ground in approximately ( g=10 m/sec2)
1) 10 sec
2) 5 sec
3) 15 sec
4) 20 sec
Solution
We know that time taken to go to maximum position is equal to time taken to return back
at maximum height final velocity v=0 v=u -gt
0=100 - 10t
t=10 sec is time taken to go to maximum height
Thus total time of flight=2 ×10=20 sec
