Question

What is the centripetal acceleration for an object of mass 50 Kg with the following specifications moving in a uniform circular motion.
Distance between the object and the axis point is 30 m. Object’s speed is 30 m/s. The acceleration of the object is ____.

  1. 0 m/s2
  2. less than 50 m/s2
  3. 50 m/s2
  4. more than 50 m/s2

Hint:

a equals v squared over r

The correct answer is: less than 50 m/s2


    m a s s equals 50 space k g
R a d i u s equals 30 space m
S p e e d equals 30 bevelled fraction numerator space m over denominator s end fraction
a subscript c equals v squared over r
equals left parenthesis 30 right parenthesis squared over 30
equals 30 space bevelled m over s squared
