Projectile motion (1 Viewer)

[RANK 1]

in physics, can i use ext1 projectile motion instead of physics projectile motion? i know that they're essentially the same thing, except that physics uses u and v, and ext1 uses proper mathematical notations. never bothered learning the physics way, so just wondering if i can.

for example Q.27 of 2004 paper

the answers give the vertical component of the velocity, but i just worked out the velocity as a single component using the time of flight equation (assumed angle is 45)

am i still correct?

Yes, you can use maths in Physics -- but never EVER Physics in maths.

As Physics > Maths -- the mathematicians get upset as whilst they are playing with their abacus, us physicists are off finding tachyonic neutrinos and the like

The Physics syllabus (and the formula sheet) gives you equations appropriate to Physics, and same with Maths.
