Easy -1.2 This is a straightforward mechanics question requiring direct application of a single SUVAT equation (v² = u² + 2as) with clearly stated values. It's a standard AS-level kinematics problem with no problem-solving required beyond selecting and applying the appropriate equation, making it easier than average.
In this question use \(g = 9.8\) m s\(^{-2}\)
A ball is launched vertically upwards from the Earth's surface with velocity \(u\) m s\(^{-1}\)
The ball reaches a maximum height of 15 metres.
You may assume that air resistance can be ignored.
Find the value of \(u\)
