Income inequality is bad enough, but wealth inequality is way worse. many people today are not equal due to there wealth. more wealthier people have better things obviously,and they also get more stuff in general. therefore, the wealth gap is way bigger because there are all sorts of "rich" "poor" and middle classman in the world today
Answer:
(D) It is moving at a constant speed
Explanation:
Before t = 1s. Due to the force, albeit small, acting on the object, since there's no static friction stopping the object from moving, this mass object would have a constant acceleration and it's velocity would be increasing.
According to Newton's 1st law, an object will stay at a constant speed if the net force acting on it is 0. After t = 1s, horizontally speaking there's no other force exerting on the mass object. There is no friction force at play here as the surface is frictionless.
Therefore the correct statement is (D) It is moving at a constant speed
(3.6 newton-second) / (600 newton) = 0.006 second
Answer:
17.69 m
Explanation:
The time it takes the brick to strike the ground is 1.90 seconds.
We can apply one of Newton's equation of linear motion to find the height of the building:
where s = distance (in this case height)
u = initial velocity = 0 m/s
t = time = 1.90 s
g = acceleration due to gravity = 9.8 m/s^2
Therefore:
s = (0 * 1.9) + (0.5 * 9.8 * 1.9 * 1.9)
s = 0 + 17.68
s = 17.69 m
The height of the building is 17.69 m.
