an object has 5.00 kg*m/s of momentum. if you double the mass and double the velocity, how much momentum would it have PLEASE HE

KIM [24]

The final momentum is 20.00 kg*m/s

Explanation:

The momentum of an object is given by:

$p=mv$

where

m is the mass of the object

v is its velocity

For the object in the problem, the initial momentum is

$p=mv=5.00 kg m/s$

Then, the mass is doubled:

m' = 2m

And the velocity is also doubled:

v' = 2v

So, the new momentum will be:

$p'=m'v'=(2m)(2v)=4(mv) = 4p = 4(5.00)=20 kg m/s$

So, the final momentum is 4 times the initial momentum.

As a motorcycle takes a sharp turn, the type of motion that occurs is called _______________ motion.

Darya [45]

Answer:

circular motion

Explanation:

As a motorcycle takes a sharp turn, the type of motion that occurs is called circular motion.

Circular motion is a movement of an object along a circular path. As this motorcycle makes the sharp turn, it is acted upon by a centripetal force which directs the motorcycle towards the center.

Therefore, circular motion is the correct answer to the question.

planets in our solar system do not revolve around the sun in perfect circles. their orbits are nore like ovals. which term do sc

luda_lava [24]

The answer is elliptical orbits. Here is are my reason for thinking it is what I know it is. All planets move in elliptical orbits, with the sun at one focus. This is one of Kepler's laws. The elliptical shape of the orbit is a result of the inverse square force of gravity. The eccentricity of the ellipse is greatly exaggerated here.
