the next Mission Impossible movie Ethan is hovering in a helicopter at a height

Question

the next Mission Impossible movie Ethan is hovering in a helicopter at a height of 1000 meters. He drops a canister that falls without air resistance for 5.0 seconds and then opens a parachute. When the parachute opens, the canister falls with a constant vertical velocity of 5.0 m/s. When the parachute is open, the canister is also blown by a 1.5 m/s breeze blowing to the East. (During the first 5 seconds the canister is essentially unaffected by the wind)

How much time passes after the release of the canister until it reaches the ground?

Please show all steps in detail

Explanation / Answer

distance travelled in first 5 secs = 0.5*9.8*5^2 = 122.5 m

so distance left = 1000- 122.5 = 877.5 m

he travels this distance with onstant speed of 5m/s,

so time taken to travel 877.5 m = 877.5/5 = 175.5 secs

so total time taken = 5+175.5 = 180.5 secs

PS: 1.5 m/s wind doesnt effect the time because its in east direction. It effects the horizontal displacement.
