A balloon is ascending at the rate of `9.8 m//s` and is 39.2 m above the ground when a package is dropped. (a) How long does the package take to reach the ground? (b) with what speed does it hit the ground ? `(g = 9.8 m//s^(2))`

A hot-air balloon is ascending at the rate of 12 m/s and is 80 m above the ground when a package is dropped over the side. (a) How long does the package take to reach the ground ? (b) With what speed does it hit the ground ?

A balloon ascending at the rate of 9.8 ms^(-1) is at a height of 39.2 m above the ground when a packet is dropped from the baloon. After how much time and with what velocity does it reach the ground? g= 9.8 ms^(-2) .

A balloon is ascending at the rate of 14 ms^(-1) at a height of 98 m above the ground when the food packet is dropped from the balloon. After how much time and with what velocity does it reach the ground ? Take g = 9.8 ms^(-2)

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. (a) With what speed does the packet reach the ground, and (b) how much time does the fall take ?

A ballon is ascending at the rate of 14 ms^-1 at a height of 98 m above ground when a packet is dropped from the balloon. After how much time and with what velocity does it reach the ground.

A stone is dropped from a height of 20 m . (i) How long will it take to reach the ground? (ii ) What will be its speed when it hits the ground? (g= 10 m//s^2)

A balloon is ascending at the constant rate of 9.8 m//sec at a height of 98 m above the ground a packet is dropped from it. If time taken by the packet to reach the ground is (1 + sqrt(3lambda))sec . Find lambda . (Use g = 9.8 m//s^(2) )

A balloon is ascending at the constant rate of 9.8 m//sec at a height of 98 m above the ground a packet is dropped from it. If time taken by the packet to reach the ground is (1 + sqrt(3lambda))sec . Find lambda . (Use g = 9.8 m//s^(2) )

A particle is dropped from a tower 180 m high. How long does it take to reach the ground ? What is the velocity when it touches the ground ? Take g=10m//s^(2) .

A packet is dropped from a helicopter, which is ascending at a rate of 16m/s , when it is at a height of 14.4m above the ground. (i) How much time it will take the packet to reach the ground? (ii) With what velocity it will hit the ground?
