TopicSUVAT in 2D & Gravity
TypeNon-Earth gravity contexts
DifficultyEasy -1.8 This is a straightforward one-step SUVAT problem requiring only substitution into s = ut + ½at² with u=0. It's simpler than typical A-level questions as it requires no problem-solving, just direct application of a single kinematic equation with given values.
Spec3.02d Constant acceleration: SUVAT formulae3.02h Motion under gravity: vector form
2 An unmanned craft lands on the planet Mars. A small bolt falls from the craft onto the surface of the planet. It falls 1.5 m from rest in 0.9 s . Calculate the acceleration due to gravity on Mars.
Question 2:
AnswerMarks Guidance
AnswerMarks Guidance
Using *suvat* equation(s) with \(s = 1.5\), \(u = 0\), \(t = 0.9\); \(s = ut + \frac{1}{2}at^2\); \(1.5 = \frac{1}{2}a \times 0.9^2\)M1 Allow for chain of equations leading to a value for \(a\)
Giving \(a = 3.70 \text{ ms}^{-2}\)A1 Allow for 3.7
