Easy -1.8 This is a straightforward single-step kinematics problem requiring direct application of v² = u² + 2as with all values given. It's multiple choice with 1 mark, requiring only substitution into a standard SUVAT equation with no problem-solving or conceptual challenge—significantly easier than average A-level questions.
A ball moves in a straight line and passes through two fixed points, \(A\) and \(B\), which are \(0.5 \text{m}\) apart.
The ball is moving with a constant acceleration of \(0.39 \text{m s}^{-2}\) in the direction \(AB\).
The speed of the ball at \(A\) is \(1.9 \text{m s}^{-1}\)
Find the speed of the ball at \(B\).
Circle your answer.
