The change in momentum of the object between 0 and 4s is 40 Ns.

What is momentum?

The momentum of an object is determined from the product of mass and velocity of the object.

The change in momentum of an object is equal to the impulse received by the object.

ΔP = J = Ft

where;

  • ΔP is change in momentum
  • J is impulse
  • F is force
  • t is time

The change in momentum of the object between 0 and 4s is calculated as follows;

ΔP = Ft

ΔP = 10 x 4

ΔP = 40 Ns
