GIVEN that ,

Initial velocity u = 0 { he starts from rest }

Acceleration a = 2m /s2

Time t =10 SECONDS

Final velocity v =?

Using first equAtion of MOTION,

V = U+ AT

V = 0 + 10× 2

V = 20 m/s.

Distance travelled s : ?

Using second equation of motion

S = UT + 1/2 at^2

= 0 + 1/2×2×100

= 100 m
