Answer» ation to be followed is :S = ut + ½ ft2…………………………………1. First, we need to solve for t when the ball is X ft above the ground on its way up. To do this, u=3 m/SEC,time t = 5 sec and we have to solve for S.solve for t:V=u + ft, here, u=0 V=3 m/sec , so, 3=0+fx5 so, f=3/5=0.6 m/sec2.Putting the values in eqn. S = 3x5–½ 0.6 x 5^2 =15-7.5= 7.5 m It was THROWN at a HEIGHT of 7.5 m………Answer |
