Hi, I am new here, and am not expecting any direct answers (I read the sticky) but I am pretty confused about this one question:
A ball is shot vertically upwards at 10m/s from a height of 5m above the ground, If friction can be ignored, what is the speed of the ball immediately before it strikes the ground?
I need to know if the formula I am using is correct:
Vf= Vi+g.T
would g (9.8m/s2) be -9.8m/s2 for this question because it uses deceleration?
thanks alot!
