Answered

A helicopter is ascending vertically with a constant speed of 5.20 m/s. At a height of 125
m above ground, a package is dropped from the helicopter.
a) How much time does it take to reach the ground?
b) How far above ground is the helicopter when the package lands?



Answer :

According to the given statement:

a)It take time to reach the ground is 3.69 s.

b)The helicopter when the package lands far above the ground is 144.18 m.

What is constant speed and example ?

Constant speed refers to a speed that remains constant throughout the duration of the motion. Constant speed is demonstrated in our example of using cruise control while driving a car.

Briefing:

Using this formula:

t= √(h/g)  

h= 125m

g= 9.2 m/s

t = √(125/9.2)

t = √13.59

t= 3.69 s

The package must touch the ground in 3.69 seconds.

From equation of motion  s = u t + 1/2 a t².

Here a= 0, then s= ut

s= 5.2x 3.69 = 19.18 m.

Total height = 19.18 + 125 = 144.18 m.

Helicopter is 144.18m far above from the ground when the package lands.
