Question

A bicycle moves along a circular path at a constant speed. The acceleration of the bicycle is Select one: O a. Toward the center of the circular path b. Tangent to the circular path O c. Zero O d. Away from the center of the circular path

Answer 1

A Bicycle moves with a constant relocity in a circular en path. We know that ce = w xr ... where o = relocity of the bicycle wa angular relocity of the - bicycle and directed upwards to the plane of paper. š= radius of the circular - orbit from Right - Hand rule we can say that the direction of relocity along the tangent of the circular orbit. again we know that accelaration of the Bicycle is a = do e = w x di from equation]

youn at from Right - Hand Rule we can say direction of accel aration a is towards the center. الی ۵ . direction of the aceelaration is towards the center. NOTE The for accelaration is not zero. Because uniform eircular motion the direction of the relocity varies smoothly as we more about the circle. Despite the constancy of speed, the direction of the motion is changing and there fore the time rate of change of relocity is nonzero – which constitures an ace el aration
Direction of $\tiny \omega$ upwards from the plane of paper..
