Answer:
The angle from the vertical is 48.72°
Explanation:
Given :
Length of rope m
Mass of man Kg
Mass of car Kg
Velocity of car
According to conservation law,
Potential energy of man is converted to kinetic energy of car moving,
We calculate height,
( ∵
)
m
This is the distance of the rope at the bottom,
So we take difference of it.
⇒
We can calculate angle between them,
48.72°
Therefore, the angle from the vertical is 48.72°
Answer:
Here is an image attached with similar questions.
The correct answer is D where acceleration is function of time.
Explanation:
The force acting on the object is constant.
There is no change in the application of forces.
And we know that Force is the product of acceleration and masses.
Newtons second law:
Regarding mass we know that it can neither be created nor destroyed.
So in we have two constant terms, constant divided by constant will give the same result as
There is no change in acceleration with respect to time
.
So the most appropriate graph where time (t) is changing on but acceleration doesn't changes is D.
The graph will be similar to and will be horizontal to the
.
Option D depicts the same.
