Two cars move down a hill at a constant velocity. Car c is much larger than car d. The car that has a greater momentum is: A. Car c because it is moving faster
B. Car d because it has less mass
C. Car c because it has more mass

C

Explanation:

When an object has a greater mass than the drag force pushing it back then it    is moving forward therefore making car C faster than car D. If car D was much smaller it wouldn't have enough mass to push past the drag force.

b) phosphorus pentoxide
