(a)
The appropriate analysis TO-DETERMINE who is correct.
(a)
Answer to Problem 105A
From the appropriate analysis the K is correct.
Explanation of Solution
Given:
For anybody sliding down on an inclined plane the acceleration is
And, the body is slides from rest, so the initial velocity
Formula used:
From the equation of motion
Calculation:
From equation of motion
Now from equation (1)
Conclusion:
This means the time of sliding down on an inclined plane does not depend on the mass of the body which slides.
So, the K is correct.
(b)
To calculate:How many seconds of difference there will be between the two times.
(b)
Answer to Problem 105A
There is no difference between their times of sliding.
Explanation of Solution
Since, the time taken to slide on an inclined plane for both man and the boy is same. So, there is no difference between their times of sliding.
Conclusion:
There is no difference between their times of sliding.
