Explanation:
s = ut + ½at^2 …. (1)
v^2 = u^2 + 2as …. (2)
v = u + at …. (3)
s = (u + v)t/2 …. (4)
where s is distance, u is initial velocity, v is final velocity, a is acceleration and t is time.
In this case, we know u = 0, a = 5m/s^2, t = 10s and we want to calculate v, so we use equation (3)
v = u + at
v = 0 + 5(10) = 50
The final velocity is 50m/s
