These questions can be solved by using the equations of motion v = u + at and s = ut + ½at².

(a) u = 0 m/s, a = 9.8 m/s², t = 1.3 s, so v = 0 + 9.8×1.3 = 12.74 m/s.

(b) s = 0×1.3 +...

I wouldn’t worry about that dream if I were you. I’d be more worried if I dreamed about myself trying to kill someone instead.
