Question

question 7 of 10
you push a cart with mass 30 kg forward, giving it an acceleration of 5 m/s².
how much force did you apply?
a. 150 n
b. 0.17 n
c. 75 n
d. 35 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 \(m = 30\space kg\) and \(a=5\space m/s^{2}\). Substitute into \(F = ma\): \(F=(30)(5)\).

Step3: Calculate the force

\(F = 150\space N\).

Answer:

A. \(150\space N\)
