Question

a car with mass of 1200 kg is driving in a circular path with a radius of 65m at a constant speed of 5.5 m/s. what is the magnitud of the net force (in newtons).

Answer 1

m = 1200kg

r = 65 m

v = 5.5 m/s

Therefore,

`\begin{gathered} F=m(v^2)/(r) \\ F=1200*(5.5^2)/(65) \\ F=1200*(30.25)/(65) \\ F=1200*0.46538461538 \\ F=558.461538462 \\ F=558.5N \end{gathered}`
