Answer to Question #15250 in Mechanics | Relativity for Jay
A 423.1-N force accelerates a go-cart and its driver from 11.3 m/s to 18.3 m/s in 5.01 s. What is the mass of the go-cart plus driver?
According to the second Newton's law
F = Ma,
where M is the mass of the go-cart with driver. We know that acceleration a is
a = (18.3[m/s] - 11.3[m/s])/5.01[s] ≈ 1.4 m/s².
So, the mass of the go-cart plus driver is
M = F/a = 423.1[N]/1.4[m/s²] = 302.2 kg.
