Why is centrifugal force is a fake force?

Answer:

We say fictitious because the actual source of the centrifugal acceleration is somewhat indirect and the experience one has results from the unbalanced forces acting on the reference frame, not a force. Note, it is an acceleration not a force. For instance, imagine yourself on a swing.

A toy car runs off the edge of a table that is 1.807 m high. The car lands 0.3012 m from the base of the table. How long does it

LekaFEV [45]

Answer:

a) $t=0.60 s$

b) $v_{ox} =0.5m/s$

Explanation:

From the exercise we have initial height and final X position

$y_{o}=1.807m$

$X=0.3012m$

a) From the concept of free falling objects we have that

$y=y_{o}+v_{oy}t+\frac{1}{2}gt^{2}$

Since the car runs off the edge of the table, that means the car is moving in x direction with $v_{oy}=0m/s$ and at the end of the motion $y=0m$

$0=1.807m-\frac{1}{2}(9.8)t^{2}$

Solving for t

t=± 0.6072 s

Since the time can not be negative, the answer is t=0.6072 s

b) To find the horizontal velocity of the car, we need to use the time that we just calculate

$X=v_{ox}t$

$v_{ox}=\frac{X}{t}=\frac{0.3012m}{0.6072s} =0.5m/s$

Find the density of an object that has a mass of 5 kg and a volume of 50 cm3

serg [7]

Density = mass/volume. 5000/50= 100 grams per cubic centimeter. No substance on Earth has anywhere near that density. Tops is about 20 for osmium and gold.

Jason rides his bicycle 1,200 meters east to the grocery store. He then turns around and travels 760 meters west to meet his fri

KiRa [710]

Since displacement is a vector quantity, it depends on direction as well as magnitude.

Taking displacement towards east as positive and towards west as negative,
Total displacement = 1200 + (-760) = 440 meters.

Since distance is a scalar quantity, it depends only upon magnitude.
Total distance = 1200 + 760 = 1960 meters.

Hope this cleared your doubt, feel free to ask any questions regarding this and have a nice day ahead! :)
