Questions
A motor car is travelling at 60 m/s on a circular road of radius 1200 m. It is increasing its speed at the rate of 4 . The acceleration of the car is:
detailed solution
Correct option is C
Tangential acceleration, at = rα = 4 m/s2Radial acceleration at = ω2r = v2r = 60×601200 = 3 m/s2Hence, resultant acceleration of the cara = at2+ar2 = 42+32 = 5 m/s2Talk to our academic expert!
