Well momentum is = to Mass*Velocity so let's use an example to figure this out
If I weighed 50kg and I was jogging at 3m/s then I broke into a run at 6m/s how will me momentum be affected?
3m/s*50kg=150
6m/s*50kg=300
So as you can see by doubling the velocity you also double the momentum
Answer:
True
Explanation:
J. Henry Alston was known as a famous African American psychologist. He was known through his detailed study of the sensations of heat and cold which is a necessity for all humans.
He however became the first African American to publish his research findings on the perception of heat and cold in a major US psychology journal which gave him recognition in his field.
I am sure the ANSWER is A !!
Given parameters:
Displacement = 8km
Velocity = 3.8km/h
Unknown:
time = ?
Solution:
Velocity is displacement divided by time.
Velocity =
Displacement = velocity x time
Input the parameters:
8 = 3.8 x time
Time = = 2.1s
The time taken is 2.1s
Answer:
A. Drag
Explanation:
This is because, since friction tends to oppose the motion of an object, and drag affects an object moving in a fluid, the more the friction, the more the drag on the object.
