Question

a body is thrown vertically upwards and takes 5 sec to reach maximum height.The distance travelled by the body will be same in (1).1st and 10th sec (2).2nd and 8th sec (3).4th and 6th sec (4).both (2) and (3)

Answer 1

heya..

ans---:-1st and 10th second 

using g = 10 m/sec^2 : 

Vo = g*t = 10*5 = 50 m/sec 


from t = 0 to t = 1 sec 

h = ((Vo*1-5*1^2)-0) = (50-5) = 45 m (up) 


from t = 9 to t = 10 sec 

h = ((Vo*10-5*10^2)-(Vo*9-5*9^2)

h= (0-450+405) = -45 m (down)

hope this will help u--:)
