A ball with a mass of #5 kg# moving at #2 m/s# hits a still ball with a mass of #3 kg#. If the first ball stops moving, how fast is the second ball moving?
2 Answers
Explanation:
One ball of mass
By the conservation of momentum in moving direction of first ball
Explanation:
We use the law of conservation of momentum, which states that:
where:
#m_1,m_2# are the masses of the two balls
#u_1,u_2# are the initial velocities of the two balls
#v_1,v_2# are the final velocities of the two balls
So, we get:
