The momentum of a 20 kilogram dog running at a speed of 8 meters per second is 160 (kg m/s).

P=mv

P=momentum

m=mass

v=velocity

The units are (kg m/s).

P=mv

P= 20kg x 8 m/s

P= 160 (kg m/s) .

Kinetic Energy = 1/2 * mass * velocity squared

KE = 1/2mV2

400 J = 1/2(20 kg)V2

multiply through by 2

800 = 20V2

40 = V2

take square root each side

6.3 m/s = velocity of dog

mass*speed squared= momentum

20 kg*8 squared or 64= 1,280 kg-m/s

momentum as an equation is:

p = mv

where m is mass

v is velocity

using this then:

p = 12 x 8

p = 96kg/ms

A 59 kg physics student is riding her 220 kg harley at 12 m/s what is their momentum?

Momentum is mass times velocity. The total mass here is 279 kg 279 * 12 = 3348. 3348 newton-seconds/kilogram-meters per second is the momentum.


What has greater momentum and athlete with a mass of 90 kg or one with 100kg and they have the same velocity?

An Athlete with a weight of 100kg, running at the same speed as a 90 kg athlete will have a greater momentum and will push the 90 kg athlete backwards.

What is the momentum of a 57 kg cheetah running north at 27 ms?

p (momentum) = m x v p = 57kg x 27 m/s p = 1539 kgxm/s The momentum of this cheetah is 1539 kg x mg/s


Which of the following has greater momentum a 500 kg car moving at 64 km a 250 kg cart moving at 12 km or a 1000 kg truck moving at 32 km?

Momentum (p) equals mass times velocity, or p=mv, and I assume that when the question says "moving at 64 km" it is referring to the cars velocity. The car will have a momentum of 32000 kg*km/s. The cart will have a momentum of 3000 kg*km/s. The truck will have a momentum of 32000 kg*km/s. The car and the truck both have a greater momentum than the cart.


Which has more momentum a football player who weighs 120 kg running at 4 meters per second or a player who weighs 102 kg running at 5 meters per second?
