Question

A runner starts from rest and has an acceleration of 3 m/s2. How fast is she running after 1.1 seconds?

Answer 1

you can use:
\[v(t)=v_0+at\]
- t and a are given
- v0 should be the initial speed, what calue do you think it takes for this problem?

Answer 2

v = u + at
v = 0 + 3x1.1
v=3.3ms-1
