Question

A cart of mass 1.91kg traveling 1.29m/s inelastically strikes a stationary mass of 0.41kg. What is the total momentum of the system after the collision? What is the final velocity of the system after thecollision?

Answer 1

Answer 2

total momentum after collision = 1.91*1.29 = 2.46

final velocity = 2.46 /(1.91+0.41) = 1.062 m/s

Answer 3

momemtum will conserve

1.91 *1.26 = (1.91+.41) V

V = 1.037327586m/s

Answer 4

total momentum= m₁v₁ + m₂v₂=1.91*1.29 + 0.41*0=2.4639kg-m/s (ans)

let final velocity=v

hence, (1.91+0.41)*v = 2.4639

or, v=1.06m/s (ans)
