A car of mass 200kg moving at a velocity of 120km/h its velocity to 60km/h in 40 second when the car hits an object 1. Calculate the momentum before hitting the object.
2. Calculate its momentum after hitting the object.
3. Calculate the change in momentum.
4. Calculate the resultant force once the car hit the object

Explanation:

To find the momentum before the collision, we must use the formula p=mv.

p=200(33.3333) m/s

p= 6666.66 (kg*m)/s

After colliding with the object, the vehicle has a negative acceleration of 00.4166667 m/s/s, the vehicle's momentum is p=200(16.66667)

p=3333.334(kg*m)/s

The momentum was decreased by 3333.332667(kg*m)/s

the resultant force is 6726.66 units (i am pretty sure that it is actually 3333.334 because it only reduces to half the original speed)
