Answer:
Speed of truck after collision = 6.28 m/s
Speed of car after collision = 22.28 m/s
Step-by-step explanation:
By law of conservation of momentum
momentum before collision = momentum after collision
![m_1u_1+m_2u_2 = m_1v_1+m_2v_2\\plugging/values\\1520*16+ 0= 1520* v_1 + 663* v_2\\24320= 1520v_1+663v_2](https://img.qammunity.org/2022/formulas/physics/college/jqzxfpvdb3vgg827vipcm6shuwj1gvncdv.png)
Since, collision is elastic
![16 = v_2-v_1///v_2 = v_1+16 ....(b)](https://img.qammunity.org/2022/formulas/physics/college/usmaytldcouw9h0siocz12wn2pfuwy2w8z.png)
solving the above two equations we get
v_1 = 6.28 m/s and v_2 = 22.28 m/s
Speed of truck after collision = 6.28 m/s
Speed of car after collision = 22.28 m/s
