Question

A box with a weight of 50 N falls through the air with a wind resistance of 20 N. What is the acceleration of the box

Answer 1

Acceleration of the box is 5.88
`ms^(-2)`

Step-by-step explanation:

Given weight, W= 50 N

We know,

W=mg

∴m=W/g

=50/9.8

= 5.10 kg

According to the stem,

W - air resistance = ma

or, 50-20=5.1a

or, 5.1a=30

or, a=30/5.1

∴a=5.88
`ms^(-2)`
