NUMERICAL QUESTION BASED ON THE MOTION UNDER GRAVITY

Asked by  | 4th Dec, 2008, 03:16: PM

Expert Answer:

Let us assume upward direction is +ve and downward direction is -ve. The initial velocity of packet is same as that of the balloon which is +14m/s as the balloon is moving in the upward direction.

Since the packet falls through 98m, h = -98m. Note that we have put a negative sign as the body falls through this distance.

Next use equations of motion to find t and v.
