a football with a mass 2 kg is in a state of idle, then a football players kick the ball with a force 50 N so the velocity of the ball become 5 m/s. how far (in meters) the soccer ball go?

given that F=50n,M=2kg v=5m/s S=? as it was stationary U=O WE KNOW f=ma therfor A=F/M=50/2 =25 WE KNOW (V^2-U^2)/2A =S,, 5^2/2into25 =0.5m
I did the same thing!
given that, F=50n, m=2kg V=5m/s AND S=? as ball was stationary so , u=0m/s WE know, F=ma a=f/m=50/2=25 t=(v-u)/a=(5-0)/25=1/5 S=ut+.5at^2=0+.5 25 1/.25 =.5m
W = △ E k
F x s = 2 1 × m × ( V t 2 − V 0 2 )
5 0 s = 2 1 × 2 × ( 5 2 − 0 2 )
s = 5 0 1 × 2 5 = 0 . 5

We know: F = m a → a = m F
And: v 2 − v 0 2 = 2 a s
Thus, v 2 = 2 m F s → s = 2 F v 2 m
So, The soccer ball travel s = 2 × 5 0 5 2 × 2 = 0 . 5 m
