Answer:
-10m/s
Explanation:
only the magnitude of the velocity will change due to the change in direction of the car.
Answer:
Rice
Explanation:
Because I can't control eating lots of rice
The change in momentum of the car is 45,000 kg m/s
Explanation:
The change in momentum of an object is given by:
where
m is the mass of the object
u is its initial velocity
v is its final velocity
For the car in this problem, we have
m = 900 kg
u = 30 m/s
v = 80 m/s
Therefore, the change in momentum is:
