Question

A 890 kg compact car is moving with velocity v1= 26(i hat)+ 18(j hat) m/s. It skids on a
frictionless icy patch and collides with a 400 kg hay wagon, which is going at a velocity
v2= 10(i hat)+ 13(j hat)m/s

If the car and the hay wagon stick together after the collision, what is their final
velocity? In what direction is their final velocity?

Answer 2

Do u know `The principle of Conservation of Linear Momentum` ?

Answer 3

According to this principle, momentum of an isolated system after and before collision is same.

Answer 4

i.e \(\sf m_1u_1+m_2u_2=m_1v_1+m_2v_2\)

\(\Rightarrow 890.(26\hat i+18\hat j )+400.(10\hat i+13\hat j)=1290.V\)

Answer 5

\(\Rightarrow V=21\hat i+16\hat j\)
