Problem

The speed

v

of a toy car is found from

v = \dfrac{s}{t}

, where the distance

s = 10.00 \pm 0.02\,\text{m}

and the time

t = 2.0 \pm 0.1\,\text{s}

. The recorded value of

v

with its uncertainty should be: a)

5.0 \pm 0.1\,\text{m s}^{-1}

b)

5.0 \pm 0.02\,\text{m s}^{-1}

c)

5.0 \pm 0.3\,\text{m s}^{-1}

d)

5.0 \pm 0.5\,\text{m s}^{-1}
