3. Two parallel forces of 100 N and 40 N act on a body in the same direction from two points A and B at a distance of 0.4 m from each other. Find the magnitude and the point of application of the
resultant of two forces.

Acar of mass m goes around a banked curve of radius r with speed v. if the road is frictionless due to ice, the car can still negotiate the curve if the horizontal component of the normal force on the car from the road is equal in magnitude to 101) a) mv2/r b) mg/2. d) mg e) tan[v2/(eg)]
