What is the speed of a 1.0 x 10^3-kilogram car that has a momentum of 2.0 x 10^4 kilogram meters per second ..

Question

... east?

Answer 1

Momentum = mass x Velocity
2x10^4 = 1x10^3 x Velocity
Velocity = 20 m/s

Answer 2

So a 1,000Kg car has a momentum of 20,000, you want he velocity eh..?

OK

P = mv;

20,000 = 1,000v

20,000/1,000= v

i would say that the velocity of o the car is v= 200 m/s

i hope i was of any help.

Answer 3

Use the formula:

momentum = mass × speed

They give you the "momentum."
They give you the "mass."
Solve for the "speed."
