Hi;

I know that the distance travelled is speed x time.

I've come across another formula for displacement s = ((u + v)t) / 2

where u= initial velocity and v = final velocity and s = displacement.

ex a football is kicked with an initial velocity on the horizontal of 17.63m/s and travels for 3 seconds. Find the distance travelled by the ball

speed x time = 17.63 x 3 = 52.89m.

s = ((u + v)t)/2 = s = ((17.63 + 0)3)/2

s = 13.2225m.

where am I going wrong?

Thanks.
