I thing i don't understand is at 0:58 when I plug in the current values of u = 7.229..., a = -9.8, v = 2(7.229) into v = u + at, I get t as - 0.7377... which is not 2. Maths is confusing huh

Moreover using the vuat equation wreaks havoc on my calculator for part b where it says non-real error. What a day...
