Explanation / Answer

speed = 2 rev/sec or 6.2831 rad/sec

tangential speed = angular speed * radius

tangential speed = 6.2831 * 0.25

tangential speed = 1.57 m/s

acceleration = v^2 / r

acceleration = 1.57^2 / 0.25

acceleration = 9.8596 m/s^2

force = mass * acceleration

force = 1.5 * 9.8596

force = 14.7894 N
