Problem
A solid steel ball of mass 200g is rolling on a horizontal surface. Its kinetic energy is measured to be 9.0J.
(i) Convert the given mass to SI units.
(ii) Calculate the speed of the ball at the instant of measurement.
(iii) The ball enters a rough patch where any ball moving slower than 10ms−1 stops within 0.25m. State, with calculation, whether this ball will cross the rough patch or come to rest within it (assume no energy losses before the patch).
