Answer:
t=3.0289s (Assuming a=9.81)
t=3s (Assuming a=10)
Explanation:
a=9.81
u=0
s=45
t = 3.0289s
Answer:
The existance of dark energy was suggested to help explain measurements, using Type Ia supernovae as distance indicators, that the expansion of the universe is speeding up and its acceleration requires a source of energy. Scientists suggested that It may be a new form of energy for which there is not yet a theoretical explanation. quantum mechanics predict that it may be the vacuum energy associated with "empty" space itself.
D the horizontal velocity is constant throughout the motion
Answer:
The image shows an object at rest, then a force pushes the car into the water. Newton's First Law describes that objects at rest remain at rest, and objects at motion remain at motion, unless they are bothered by a force. This law comes into play with the image because the object is first seen at rest, on the top of another object. Then it is seen falling, and is now in motion at it descends into the water. Newton's Second Law, F = MA, is seen in the image is the object accelerates into the water from the force. Newton's Third Law, which states 'for every action there is an equal but opposite reaction', is in this image as the object is falling, then makes contact with the water.
