Question

question 10 of 10
you push a cart with mass 20 kg forward, giving it an acceleration of 2 m/s².
how much force did you apply?
o a. 40 n
o b. 0.1 n
o c. 18 n
o d. 10 n

Explanation:

Step1: Recall Newton's second law

Newton's second law is \(F = ma\), where \(F\) is force, \(m\) is mass, and \(a\) is acceleration.

Step2: Substitute the given values

Given \(m = 20\space kg\) and \(a=2\space m/s^{2}\). Substitute into \(F = ma\), so \(F=(20\space kg)\times(2\space m/s^{2})\).

Step3: Calculate the force

\(F = 40\space N\).

Answer:

A. 40N
