Question

An object of mass 3.03 kg, moving with an initial velocity of 5.04 i m/s, collides with and sticks to an object of mass 2.31 kg with an initial velocity of -3.85 j m/s. Find the final velocity of the composite object. v = (the initial velocity of object m_2 is in the J direction, Will this have any influence on the final velocity in the i direction? i + If the initial y velocity of object m_1 is zero and the initial y velocity of object m_2 is negative, can the combined object be moving in the positive y direction after the collision? J) m/s

Explanation / Answer

here,

mass of first object , m1 = 3.03 kg at speed , u1 = 5.04 i m/s

mass of seccond object , m2 = 2.31 kg at speed , u2 = - 3.85 j m/s

let the final velocity be v


using conservation of momentum

m1 * u1 + m2 * u2 = (m1 + m2) * v

3.03 * 5.04 i - 2.31 * 3.85 = ( 3.03 + 2.31) * v

v = (2.86 i - 1.67 j ) m/s

the final velocity of the composite object is (2.86 i - 1.67 j ) m/s
