If a force of 30.6 kg acts on a 60 kg mass, calculate the resulting acceleration. (1 k.g of force = 9.8 newtons)

Options

A. `5m//sec^2`
B. `2m//sec^2`
C. `0.5m//sec^2`
D. `9.8m//sec^2`

Answer

A

Explanation

Use f=ma when m =60 kg and f =30.6 kg force (convert to newtons)
f=(30.6)(9.8)=300 newtons
a=f/m=300 kg /60 `a=5m//sec^2`
