Question

Find the acceleration of an object when the force is 850 N and the mass is 85 kg.

7.3 x 104 m/s2
10 m/s2
0.1 m/s2
0 m/s2

Answer 1

There are two forces acting upon the skydiver - gravity (down) and air resistance (up). The force of gravity has a magnitude of m•g = (72 kg) •(9.8 m/s/s) = 706 N. The sum of the vertical forces is

∑Fy = 540 N, up + 706 N, down = 166 N, down

The acceleration of the skydiver can be computed using the equation ∑Fy = m•ay.

ay = (166 N, down) / (72 kg) = 2.3 m/s/s, down

Answer 2

Answer:

10 m/s square

Explanation:

f=ma

a=f/m
