A ball of mass 0.2 kg tied to string and whirled in a chorizontal circle of radius 0.4 m if ball makes 10 complete revolution in 4secs determine linear speed centripetal acceleration and centripetL force??

Answer 1

angular speed: 10*2PI*r/4
given r.

linear speed: angularspeed*r

centripal acceleration: w^2 * r

force: mass*centripetal acceleration
