As the coaster car rolls down the track from A to E, the <u>potential energy</u> values decrease and the <u>kinetic energy</u> value increase and the<u> </u><u>total mechanical energy</u> values remain constant. The <u>potential energy</u> is greatest at point A and smallest at point E. However, the <u>kinetic energy</u> is smallest at point A and largest at point E.
According the principle of conservation of mechanical energy, as the potential energy decreases, the kinetic energy increases.
At point A, the coater has maximum potential energy.
At point E, the coaster has maximum kinetic energy.

Based on the principle of conservation of mechanical energy, if the second simulation occurs at the same condition as the first, the height reached by coaster will be same.

The centripetal acceleration is given by
where v is the tangential speed and r the radius of the circular orbit.
For the car in this problem,
and r=40 m, so we can re-arrange the previous equation to find the velocity of the car:
The answer would be
C) all three galaxies are moving further away from Earth they were in 10,000 BC
Answer:
In metric prefixes, if a meter were divided into 100 equal-sized subunits, a single unit would be called a centimeter.
Explanation:
Here we asked to divide 1 meter in to 100 equal parts.
Let us find out what is the length of piece when 1 m is divided in to 100 equal parts.
Length
That is length of 1 m divided into 100 equal parts is 0.01m.
We know that 0.01 m is 1 centimeter.
So, in metric prefixes, if a meter were divided into 100 equal-sized subunits, a single unit would be called a centimeter.
Answer:
Maximum speed, v = 36 m/s
Explanation:
Given that,
The radius of the curved road, r = 120 m
Road is at an angle of 48 degrees. We need to find the maximum speed of stay on the curve in the absence of friction. On a banked curve, the angle at which it is cant is given by :
g is the acceleration due to gravity
v = 36.13 m/s
or
v = 36 m/s
So, the maximum speed to stay on the curve in the absence of friction is 36 m/s. Hence, this is the required solution.
