Pauline and her poodle puppy Fifi are jogging around a circular track of radius r = 100 m at a constant speed v = 3 m/s. Is the centripetal force on Pauline
Answer: Both Pauline and Fifi share the same centripetal acceleration: v^2 (3 m/s)^2 a = ------- = ------------ = 0.09 m/s^2 r 100 m The centripetal force on each one must be F = m * a = (mass) * 0.09 m/s^s Since Pauline has a greater mass than her little puppy, she must experience a greater centripetal force.
