Quick questions on Further kinematics and projectiles: variable acceleration and projectile motion - CCEA A-Level Further Maths

4short Q&A pairs drawn directly from our worked dot-point answer. For full context and worked exam questions, read the parent dot-point page.

What is projectile motion?
Show answer
Mixing the horizontal and vertical motions of a projectile. Horizontal velocity is constant; vertical motion has acceleration −g-g. Keep the two component calculations separate and link them only through time.
What is q1?
Show answer
A particle has displacement s=2t3s = 2t^3. Find its velocity at t=1t = 1. [2 marks]
What is q2?
Show answer
A projectile is launched at 30 m s−130\,\text{m s}^{-1} horizontally. What is its horizontal velocity after 2 s2\,\text{s}? [1 mark]
What is q3?
Show answer
For variable acceleration, how do you find displacement from velocity? [1 mark]
