Moderate -0.5 This is a standard projectile motion problem requiring straightforward application of SUVAT equations in two dimensions. Students need to find vertical velocity using v² = u² + 2as, then combine with horizontal velocity using Pythagoras and trigonometry. While it involves multiple steps, it's a routine textbook exercise with no conceptual challenges beyond basic mechanics.
A particle is projected horizontally with a speed of 6 m s\(^{-1}\) from a point 10 m above horizontal ground. The particle moves freely under gravity. Calculate the speed and direction of motion of the particle at the instant it hits the ground. [6]
