I believe it would be 2m/s.
Momentum = mass x velocity
So both mass and velocity affect an object's momentum.
Answer:
A. That enough light of any frequency would cause electrons to flow.

A P E X
Nope, color change can also occur during a physical change.
Answer:
u= 187.61 ft/s
Explanation:
Given that
g= - 32 ft/s²
The maximum height ,h= 550 ft
Lets take the initial velocity = u ft/s
We know that
v²=u² + 2 g s
v=final speed ,u=initial speed ,s=height
When the object reach at the maximum height then the final speed of the object will become zero.
That is why
u²= 2 x 32 x 550
u²= 35200
u= 187.61 ft/s
That is why the initial speed will be 187.61 ft/s
