Rita is riding a 7.0 kilogram bike at a velocity of 15 meters/second. rita’s mass is 42 kilograms. what is her momentum?

The correct answer is 735 kg m/s.

Explanation:

The expression of the momentum in terms of mass and velocity is as follows;

p=mv                                                            (1)

Here, m is the mass of the object and v is the velocity.

It is given in the problem that Rita is riding a 7.0 kilogram bike at a velocity of 15 meters/second. Rita’s mass is 42 kilograms.

Calculate the total mass, M (Mass of the bike and mass of Rita).

M= 7 kg + 42 kg

M= 49 kg

Calculate the momentum.

Put m= 49 kg and v= 15 m/s in the equation (1).

p=(49)(15)

p= 735 kg m/s

Therefore, the momentum of the speedboat is 735 kg m/s.

it is easily magnetized.
