How to do 180th question?
1 Answer
Its an interesting question...ANS must be 15cm/s.
Explanation:
According to the question, R=10 (it doesn't matter for the slope), so the circle is given by
Since, height=
Now the slope is given by
Now, given a velocity of 20m/s to the left, we know that the sphere will have a velocity of
- YOU MAY BE THINKING WHY IS THE VELOCITY ??
- WELL HERE'S WHY ,
Let's say the height of the intersection of the wedge and the circle at a given time is
We know the slope of the sphere is
The velocity of the wedge is given by
We know
I HOPE IT HELPS!!
