Question

A uniform solid sphere of mass m and radius R is kept on the rough horizontal surface with co-efficient of friction mu= 1/3 as shown in figure. An impulse of J equals m v subscript 0 is applied tangentially on the sphere at an angle 37° with the horizontal as shown in the figure. (assuming  J >> mgdt, g = 10 m/s2, open tan invisible function application 37 to the power of ring operator equals 3 divided by 4 close parentheses )

Find the time after which sphere is in pure rolling motion.

  1. fraction numerator 18 v subscript 0 over denominator 175 end fraction
  2. fraction numerator 7 v subscript 0 over denominator 175 end fraction
  3. fraction numerator 4 v subscript 0 over denominator 35 end fraction
  4. fraction numerator 3 v subscript 0 over denominator 35 end fraction

The correct answer is: fraction numerator 3 v subscript 0 over denominator 35 end fraction
