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

Answer:

The parachute to open in 15 sec.

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

$v=\dfrac{d}{t}$

$t=\dfrac{d}{v}$

Where, d = distance

t = time

v = velocity

Put the value into the formula

$t=\dfrac{500}{120\times\dfrac{5}{18}}$

$t=15\ sec$

Hence, The parachute will be open in 15 sec.
