Which has more momentum, a 3.0 kg mass moving at 9.0 m/s or a 5.0 kg mass moving at 5.0 m/s

Object 1 with a mass of 3.0kg and velocity of 9.0m/s has more momentum( 27 kg-m/s ) compared to object 2.

Given the data in the question;

We calculate the momentum of object 1 and object 2, using the expression for momentum:

Where m is mass and v is velocity

For object 1;

Momentum of object 1 is 27 kg-m/s

For object 2;

Momentum of object 2 is 25 kg-m/s

Therefore, Object 1 with a mass of 3.0kg and velocity of 9.0m/s has more momentum( 27 kg-m/s ) compared to object 2.

A 3.0 kg mass moving at 9.0 m/s has more momentum than taht of a 5.0 kg mass moving at 5.0 m/s

Explanation:

given two masses m1 and m2 and their corresponding velocities v1 and v2

m1 = 3 kg

m2 = 5 kg

v1 = 9 m/s

v2 = 5 m/s

To calculate momentum of the masses:

We know that the momentum is given by the equation:

p = mv, where m is mass and v is velocity

momentum of mass m1 , p1 = m1 x v1

                                             =  3 x 9 = 27 kg.m/s

momentum of mass m2, p2 = m2 x v2

                                              = 5 x 5 = 25 kg.m/s

Hence p1>p2

Comparing above momentum value, it is inferred that the momentum of mass 3.0 kg is more that the momentum of mass 5.0 kg.
