Question

- A 300 kg box of supplies is dropped from a plane and has a parachute attached, if it accelerates down

at 2m/s? what resistive force does the parachute supply?

Answer 1

2340 N

Step-by-step explanation:

There are two forces on the box. Weight force pulling down and resistive force pushing up.

Sum of forces in the y direction:

∑F = ma

F − mg = ma

F = mg + ma

F = m (g + a)

F = (300 kg) (9.8 m/s² + (-2 m/s²))

F = 2340 N
