1) Which of the following has the greatest momentum? Explain.
v = 5 m/s
m = 1.2 X 10 kg
m = 1800 kg

m=1800 kg has the   greatest momentum

Explanation:

Linear momentum is defined as the product of mass and velocity of a body. It is directly proportional to mass and velocity and is given by the expression

P=mv

where P denotes linear momentum,m denotes mass and v denotes velocity.

given that

velocity of both objects is v=5 m/s

Mass of the first object m=

Mass of the second object m=1800 kg

velocity of both objects is same. The second object has higher mass than first.

When mass increases, momentum increases with it.

Thus the second object with m=1800 kg has higher momentum than first.
