Easy -2.0 This is a trivial one-mark question requiring only the formula a = (v-u)/t with straightforward substitution (1.28/1.8 ≈ 0.71 cm/s² = 0.0071 m/s²). The multiple choice format and unit conversion are the only potential pitfalls, but this is far below average A-level difficulty—essentially testing basic recall of a single kinematics formula.
A garden snail moves in a straight line from rest to 1.28 cm s\(^{-1}\), with a constant acceleration in 1.8 seconds.
Find the acceleration of the snail.
