Question

A skydiver jumps from an airplane traveling 120. km/hr at a height of 1000. m. If his parachute must open 500. m above the ground, how long does he have for the chute to open?

Answer 1

The parachute to open in 15 sec.

Step-by-step explanation:

Given that,

Velocity = 120 km/hr

Height = 1000 m

If his parachute must open 500. m above the ground.

We need to calculate the time for parachute to open

Using formula of time

`v=(d)/(t)`

`t=(d)/(v)`

Where, d = distance

t = time

v = velocity

Put the value into the formula

`t=(500)/(120*(5)/(18))`

`t=15\ sec`

Hence, The parachute will be open in 15 sec.
