Question
A disc of radius R is rolling purely on a flat horizontal surface, with a constant angular velocity. The angle between the velocity and acceleration vectors of point P is
Options
A.Zero
B.45o
C.135o
D.tan-1 (1/2)
Solution
∴ For purely rolling
v = Rω
So at point ′P′ the resultant velocity makes 45o with horizontal ′x′ axis and it is also the angle between ′v′ and ′a′
v = Rω
So at point ′P′ the resultant velocity makes 45o with horizontal ′x′ axis and it is also the angle between ′v′ and ′a′
