Question

question 3 of 10
you are riding a bicycle. you apply a forward force of 100 n, and you and the
bicycle have a combined mass of 80 kg. what is the acceleration of the
bicycle?
a. 1.8 m/s²
b. 1.5 m/s²
c. 0.8 m/s²
d. 1.25 m/s²
5.1.4 quiz: force problems

Explanation:

Step1: Recall Newton's second law

Newton's second law is \(F = ma\), where \(F\) is the force, \(m\) is the mass, and \(a\) is the acceleration. We need to solve for \(a\), so the formula becomes \(a=\frac{F}{m}\).

Step2: Substitute the given values

Given \(F = 100\space N\) and \(m=80\space kg\). Substitute these into the formula: \(a=\frac{100}{80}\).

Step3: Calculate the value

\(a=\frac{100}{80}=1.25\space m/s^{2}\)

Answer:

D. \(1.25\space m/s^{2}\)
