A particle whose mass is 2 kg moves with a speed of 44 m/s on a curved path. The resultant force acting on the particle at a particular point of the curve is 30 N at `60^(@)` to the tangent to the curve, as shown in fig. At the point, find (a) the radius of curvature of the curve and (b) the tangential acceleration of the particle.

Answer

(a) `149m ` (b) `7.5m//s^(2)`
