Question

A small, 0.100 kg cart is moving at 1.20 m/s on a frictionless track when it collides with a larger, 1.00 kg cart at rest. After the collision, the small cart recoils at 0.850 m/s. What is the speed of the large cart after the collision

Answer 1

Answer:

$V_2=0.205m/s$

Explanation:

From the question we are told that

Moving Mass $m_1=0.1kg$

Velocity of cart $u_1=1.20 m/s$

Stationary Mass $m_2= 1.00 kg$

Recoil velocity $V_1=0.850 m/s$

Generally the equation of momentum is mathematically given by

$m_1u_1+0=m_1v_1+m_2v_2$

$(0.1)(1.20)+0=(0.1)(-0.850)+(1)v_2$

$V_2=0.205m/s$

Therefore speed of the stationary mass after collision is $V_2=0.205m/s$
