Answer:
455 kg m/s
Explanation:
The impulse acted on the object is equal to the change in momentum of the object:
and the change in momentum is equal to the product between the mass of the object and the change in velocity:
where:
m = 25 kg is the mass of the object
u = 12 m/s is the initial velocity of the object
v = -6.2 m/s is the final velocity of the object (we have taken a negative sign because the object now moves in the opposite direction)
Therefore, the impulse is
