The cyclist begins to move from a state of rest and moves in a straight line with uniform acceleration.

The cyclist begins to move from a state of rest and moves in a straight line with uniform acceleration. In 10 s after the start of movement, its speed becomes equal to 5 m / s. With what acceleration does the cyclist move?

Acceleration is the ratio of the increase in speed to the increase in time during which the speed changed, therefore:

a = (v – v0) / t.

Because the cyclist began to move, then his initial speed was zero, thus:

a = v / t = 5/10 = 0.5 m / s².

Answer: the cyclist was moving at an acceleration of half a meter per square second.
