A motor cycle travelling at 10 m/s accelerates at 4m/s for 8s.
what is it final velocity? ​

Final velocity be v

• From the first newtons equation of motion:

v » final velocity which is required.

u » initial velocity, u = 10 m/s

a » acceleration, a = 4 m/s²

t » time, t = 8 seconds

Substitute:

i wanna say it’s between b and d, leaning more towards b.

the answer is b ) square root of 5
