Momentum and CollisionMedium

Question

Two blocks A(3 kg) and B (2 kg) resting on a smooth horizontal surface is connected buy a spring of stiffness 480N/m. Initially the spring is under formed and a velocity of 2 m/s is imparted to A  along the line  of the spring  away from B. the maximum extension meters of the spring away from B. The maximum extension in meters to the spring during subsequent motion is

Options

A.
B.
C.
D.0.15

Solution

COLM : 3 × 2 = (3 + 2) v ⇒ v = m/s
COME : × 3 × 22 = × 5 × × 480 × x2.
⇒ x = m
