A1,000-kg vehicle traveling 4 m/s eastward collided with another vehicle, at which point it moved 1 m/s westward. what was the vehicle's change in momentum?
a. 1,000 kg • m/s
b. 3,000 kg • m/s
c. 4,000 kg • m/s
d. 5,000 kg • m/s

Change in momentum will be 5000 kg-m/sec

So option (d) will be the correct option

Explanation:

We have given mass of the vehicle m = 1000 kg

Let the velocity in eastward direction is positive so velocity in westward direction will be negative

So velocity in eastward direction

Velocity in westward direction

We know that change in momentum is given by  

So option (d) will be the correct option

c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head

hope this !

like poles repel so keep pushing north to north and repels funny to see this
