a mass of 0.2 kg is whirled at 12 revolutions in 2 sec in a horizontal circle at the end of o string0.8m long.(a)angular velocity (b)linear velocity (c) central acceleration (d) central force

Answer 1

angular velocity= angle/time=12*2PI/2 rad/sec

linear velocity= r*angularvelocity

central acceleration= w^2 * r

force= mass* centralacceleration
