Easy -1.8 This is a 1-mark question requiring only direct recognition that acceleration is the coefficient of t in a linear velocity-time equation (v = u + at). It's pure recall with no calculation or problem-solving, making it significantly easier than average A-level questions.
A particle is moving in a straight line with constant acceleration \(a\) m s\(^{-2}\)
The particle's velocity, \(v\) m s\(^{-1}\), varies with time, \(t\) seconds, so that
$$v = 3 - 4t$$
Deduce the value of \(a\)
Circle your answer.
