Answer» The masses of two BLOCKS are 2kg and 1kg, the time is 2sec.The acceleration of masses is given as,a= (m 2 +m 1 )(m 2 −m 1 )g = (2+1)(2−1)g = 3g The acceleration of the centre of MASS is given as,a cm = (m 2 +m 1 )(m 2 −m 1 )× 3g = (2+1)(2−1)× 3g = 9G The distance travelled by centre of mass is given as,s= 21 at 2 = 21 × 9g ×4=2.22mThus, the distance travelled by the centre of mass is 2.22m.Explanation:hope it is useful |
