Mr Lusa is turning his car 1,000kg at 11.17m/s (25mph). If he turns with a radius of 10m, what centripetal force is necessary for his car to make the turn?
Please show work. Thanks!

The equation for centripetal force is F=(m(v^2))/r, where F is the centripetal force, m is the mass in kg, v is the velocity in m/s, and r is the radius in m. Put in your values into the equation, and you should get a result that is close to 12476.89 newtons (please note that this is the exact value; if your teacher wants the answer in proper sig figs, you may have to use scientific notation).

Please refer to my source if you want to see the formula for centripetal acceleration more clearly, or any of the other formulas for circular motion.
