when acceleration is = a= 3 (m/s²) , displacement is = s= 8.4 (m) and velocity is = v = 10 (m/s²) in formula v²= u²+2as .find the initial velocity=u ?
tell me with explanation pls

Answer:
putting values in formula we have
10²= u²+2×3×8.4
100= u² + 50.4
u²= 100-50.4
u² = 49.6
u = √49.6
u= 7.042 m/s answer
