A) 10 m, 25 m
B) 5 m, 137.1 m
C) 15 m, 56 m
D) 15 m, 25 m
Correct Answer: C
Solution :
Velocity of balloon at t = 2 s is \[v=0+5\times 2=10m/s\] Height of balloon when ball has been drooped \[h=\frac{1}{2}\times 5\times {{2}^{2}}=10m\]from this instant the motion of ball is under gravity, having initial velocity same as that of balloon.You need to login to perform this action.
