This is for grade 11 and I'm in college studying this before a big test. Your Newton's Laws and Kinematics videos helped me more than my professors mickey mouse powerpoints. Blessings!

Last answer isn't it meant to be the y component divided by the x?

Could you use the X direction to find time?

I’m a bit confused on why we don’t do anything about the Time component for the first question? The only known variables were the acceleration and V1X, does T not matter because the acceleration was zero and multiplying the two would be zero regardless?

Great question Julius! It is totally possible calculate Δt from the information given in that first problem. You can use the equation y_2 = y_1 + v_{1y}Δt + 0.5aΔt^2 to solve for time (don't forget you'll need the quadratic formula to solve it!). However, since the question doesn't ask us to calculate time, there's really no need to waste your time (pun intended) solving for it. The awesome thing about the kinematics equation we used here, (v_2)^2 = (v_1)^2 + 2a(y_2 - y_1), is that it actually _comes from_ that quadratic-looking kinematics equation with time in it, but it allows you to jump straight to calculating final velocities without having to first solve for time. I hope that helps!
