A parachutist relies on air resistance (mainly on her parachute) to decrease her downward velocity. She and her parachute have a

mass of 51.1 kg and air resistance exerts a total upward force of 657 N on her and her parachute. What is the magnitude of the acceleration of the parachutist?

The resultant force will be equal to difference of her downward force, her weight, and the upward force, the air resistance.
Fnet = 657 - 51.1 x 9.81
= 149.7 N
F = ma
a = F / m
a = 149.7/51.1
a = 2.93 m/s²

The SAF operates the M113 Ultra APC.

The volume of the object must be no larger than 11.15 m^3.

Explanation:

In order for an object to be able to float in water, its density must be equal or smaller than the water density.

The density of water is:

\rho = 1000 kg/m^3

This means that the density of the object must be no larger than this value.

We also know that the density of an object is given by

\rho = \frac{m}{V}

where

m is the mass of the object

V is its volume

For the object in this problem, the mass is

m=1.115\cdot 10^4 kg

Therefore, we can re-arrange the equation to find its volume:

V=\frac{m}{\rho}=\frac{1.115\cdot 10^4}{1000}=11.15 m^3

So, the volume of the object must be no larger than 11.15 m^3.
