A plank is moving with a velocity 4m/s a disc of radius 1m rolls without slipping on it
Answers
The velocity of centre of the disc is 7 m/s.
Explanation:
Correct statement:
A plank is moving with a velocity of 4 m / s e c. A disc of radius 1 m rolls without slipping on it with an angular velocity of 3 r a d / s e c as shown in figure. Find out the velocity of centre of the disc.?
Solution:
Since it is pure rolling the velocity of the point at the bottom will be equal to velocity of plank.
Thus at point A
V(cm) - RW = 4
V(cm) - 3 = 4
V(cm) = 7 m/s
Hence the velocity of centre of the disc is 7 m/s.
