Question

a 55 kg sled is experiencing 150 newtons of force to the right and 60 newtons of force to the left. calculate the sleds acceleration. known unknown (what are we trying to find?) net force = f_net = (m)(a) rearrange formula substitute known values answer with units

Explanation:

Step1: Calculate net force

Net force \(F_{net}=F_{right}-F_{left}\). Given \(F_{right} = 150N\) and \(F_{left}=60N\), so \(F_{net}=150 - 60=90N\)

Step2: Rearrange Newton's second law formula

From \(F_{net}=m\times a\), we can solve for \(a\) as \(a=\frac{F_{net}}{m}\)

Step3: Substitute known values

Given \(m = 55kg\) and \(F_{net}=90N\), then \(a=\frac{90}{55}\approx1.64m/s^{2}\)

Answer:

The sled's acceleration is approximately \(1.64m/s^{2}\)
