Question

If a 50 kg student is pushed in a rolling chair with a force of 20 N, what is the student’s acceleration?

2.5 m/s2
4 m/s2
1,000 m/s2
0.4 m/s2

Answer 1

0.4m/s²

Step-by-step explanation:

Given parameters:

Mass of student = 50kg

Force = 20N

Unknown:

Acceleration = ?

Solution:

From Newton's second law of motion,

Force = mass x acceleration

Acceleration =
`(Force )/(mass)` =
`(20)/(50)` = 0.4m/s²
