A truck weighs 6000 lb. The truck is going around a curvewith a radius of 650 feet. The maximum friction force the road can exert on the tires is 1125 lb. it wants me to calculate the velocity in ft/sec
And by Newton's second law, we know that F=ma. Since the car is moving in a circular path, he is accelerating. The only force that is pointing towards the center of the circle is friction. So:
F=ma
Force of friction = m*(v^2/r)
1125lb = 6000lb*(v^2/650ft)
v=11.039701082909808568455053408699 ft/s
