Question

A car of mass m going around a curve of radius r at constant speed v experiences a net force F. What is the net force on a truck of mass 5m traveling around a curve of radius 5r with constant speed 5v?

Answer 1

a Given that the mass of the truck is 5m, moves along a curve having radius of, 5r and the speed of the truck is 5v.

The formula of the net force is

`F=(mv^2)/(r)`

Here, m is the mass, v is the speed and r is the radius.

Substituting the values of a truck in the net force formula, we get

`\begin{gathered} F=(5m*(5v)^2)/(5r) \\ =(25mv^2)/(r) \end{gathered}`
