reaches a speed of 6m/s after travelling
with uniform acceleration for 3s. What is his
acceleration?​

Answer 1

Resposta:

yeah

Explicação:

Answer 2

Answer: $a = 2m/s^{2}$

You need to use this equation: V(t) = $V_{0} + a \cdot t$.  "A motorcyclist starts from rest." ⇒ $V_{0} = 0m/s$.

Thus, V(t) = at.

Now, see that $v(3) = 6m/s$, so, $6 = a \cdot 3, a = 2m/s^{2}$

$a = 2m/s^{2}$

This is your answer.
