Solve the all parts of given problem:
Problem: A hot-air balloon is ascending at a rate of 14 m/s at a height of 98 m above the ground when a packet is dropped from it.
Part A: With what speed does the packet reach the ground?
Part B: How much time does the fall take?
I need help to find with what speed the packet reaches the ground.
