Answer:
the answer to your question is 2.5
Explanation:
Answer:
Velocity of the car at the bottom of the slope: approximately
.
It would take approximately
for the car to travel from the top of the slope to the bottom.
Explanation:
The time of the travel needs to be found. Hence, make use of the SUVAT equation that does not include time.
- Let
denote the final velocity of the car. - Let
denote the initial velocity of the car. - Let
denote the acceleration of the car. - Let
denote the distance that this car travelled.
.
Given:
Rearrange the equation
and solve for
:
.
Calculate the time required for reaching this speed from
at
:
.
A common misconception is that scientific theories are rudimentary ideas that will eventually graduate into scientific laws when enough data and evidence have been accumulated. A theory does not change into a scientific law with the accumulation of new or better evidence.
