the small 2kg block A slides down the curve path and passes the lowest point B with a speed 4 m/s. If the radius of the curvature path at B is 1.5 m, determine the normal force N exerted on the block by path at this point. Is knowledge of the friction properties necessary? solution of this question

Answer 1

normal force will be mg+ centripetal or

mg+mv^2/r

Answer 2

31.6
