The centripetal force of an object of mass m is given by f(r)=mv2r, where v is the speed of rotation and r is the distance from the center of rotation. find the rate of change of centripetal force with respect to r of an object with mass 1000 kilograms, velocity of 13.89m/s and a distance from the center of rotation of 200 meters. do not include units in your answer, and round to the nearest thousandt

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
