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 horizontal motion?
Show answer
No horizontal force acts (air resistance is ignored), so horizontal velocity is constant.
What is q1?
Show answer
Define the term "projectile" as used in HSC Physics and state the two simplifying assumptions made about its motion. [2 marks]
What is q2?
Show answer
A stone is thrown from the Sydney Harbour Bridge deck 49.0 m49.0 \text{ m} above the water at v0=18.0 m/sv_0 = 18.0 \text{ m/s} angled 2525^{\circ} below horizontal. Calculate the horizontal distance to the splashdown. [4 marks]
What is q3?
Show answer
A motocross rider leaves a 5.05.0^{\circ} ramp at 20 m/s20 \text{ m/s}. (a) Find the time spent airborne if landing height equals launch height. (b) Find the maximum height above the ramp.
