two bodies of masses and m2 connected by an ideal massless spring of constant k. the coefficient of friction between the bodies and surface is p. the minimum force required to shift the body m2 is f. then: '00000^ m2 (a) the mass will first accelerate then deaccelerate (b) the mass mx is first accelerated upto a maximum velocity vq and then declerates to come to rest (c) the mass will accelerate co
