Question

8. (a) A cyclist goes around a circular track once every 2minutes. If the radius of the circular track is 105meters, calculate his speed (Given π = 22/7).

(b) Draw the V-t graph for a nonuniform retardation.

Answer 1

Answer:

(a) A cyclist goes around a circular track once every 2minutes. If the radius of the circular track is 105meters, calculate his speed (Given π = 22/7).

(b) Draw the V-t graph for a nonuniform retardation.

Answer 2

a) Refer to the attachment ✔️✔️

b) Vt graph for non uniform retardation

The straight downward angle shows the decreasing velocity with uniform acceleration, i.e. retardation. Velocity-time graph (In the case of non-uniform acceleration): In case of a body moving with non-uniform acceleration the velocity-time graph becomes a curve [Fig (a) and (b)].
