Which of the following has the largest momentum? a. 5kg bowling ball moving with a velocity of 2m/s
b. A 4kg rock rolling down a hill with a velocity of 3m/s
c. A 200kg rock sitting on top of a hill that is 5m height.
d. 0.0025kg bullet that is moving with a velocity of 200m/s

Option b

Explanation:

The formula of momentum is

where p is the momentum , m is the mass in kg and v is the velocity in m/s, so

a) momentum is

b) momentum is

c) momentum is

here since the rock is sitting on top of a hill which means the object is stationary or in other words the object is at rest, which means if an object is at rest the velocity is 0m/s so momentum is zero of a stationary object because

d) momentum is

so the highest momentum is in part b which is 12 so option b is our answer.

the independent variable, the one that is intentionally manipulated, is whether or not the car hits the barrier.

the dependent variable, the one that you measure the response in, is the distance that the washers travel.
