LUCKY_DIMON [66]
At some time during her drive she backed up with a substantial negative. ( backwards) acceleration. Since the pocket book is not physically connected to the seat it is free to move. Upon rapid negative acceleration the pocket book remains in its position while the car accelerates backwards away from it. this demonstrates Newtons 1st law of motion. The first law is the law of inertia. Which states, an object at rest. ( pocketbook) will remain at rest and an object in motion will continue in motion at constant velocity, unless acted upon by some outside force to change its motion.

according to karl popper, a discipline that claims to be a science is really a pseudoscience like astrology if it:
Leona [35]

A scientific theory should make testable predictions and if those predictions are found to be incorrect the theory should be dismissed.

He argued that science advances best through the use of deductive reasoning, known as critical rationalism, as its primary emphasis. Popper coined the term critical rationalism to describe his philosophy. Popper rejected the empiricist view that basic statements are infallible.

Karl Popper was a scientific realist against his will. Despite his own limitations regarding the forms of acceptable scientific reasoning and the extent of empirical evidence, he advocated a very real conception of scientific goals and outcomes. A significant contribution stems from his rejection of induction in empirical science.

A computational model predicts the speed of a roller coaster car at different heights given its speed at the lowest height of it
s2008m [1.1K]

Answer:

the answers, the correct one is A   v= 22.5 m/s

Explanation:

We can solve this problem using the concepts of conservation of mechanical energy

Starting point. Lowest point of the trajectory

       Em₀ = K = ½ m v₀²

Final point. When it is at a height of y = 20 m

       Em_{f} = K + U = ½ m v² + mg y

     

how energy is conserved

         Emo = Emf

         ½ m v₀² = ½ m v² + m g y

         v² = v₀² + 2 g y

 

let's calculate

         v²2 = 30 2 + 2 9.8 20

         v² = 508

         v²= ra 508

         v² = 22.54 m / s

When checking the answers, the correct one is A

A 60.0 kg student runs up a flight of stairs in Rockefeller Hall a height of 4.0 m in a time of 6.0 s. What average mechanical p
Andrews [41]

Answer:

400watts

Explanation:

Power is defined as the amount of energy expended in a specific time. It is also defined as the change in work done with respect to time.

Mathematically,

Power = Workdone/time

Work done = Force×distance

Power = Force × Distance/Time

Given force = mass× acceleration due to gravity

Force = 60×10 = 600N

Distance covered = 4.0m

Time taken = 6.0seconds

Power expended = 600×4/6

Power expended = 400Watts

The average mechanical power (in W) required to do this is 400Watts
