Question

1. how much force is acting on a skateboard that has an acceleration of 3.4 m/s² if the mass of the skateboard is 5 kg?

a. 13 n
b. 17 n
c. 8 n
d. 12 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 \(m = 5\space kg\) and \(a=3.4\space m/s^{2}\), substitute into the formula: \(F=(5)(3.4)\).

Step3: Calculate the force

\(F = 5\times3.4=17\space N\)

Answer:

B. 17 N
