- D 5 m/s 2
Step-by-Step Verified Solution
Velocity towards east direction, v 1 _ = 30 i ^ m/s
Velocity towards north direction, v 2 _ = 40 j ^ m/s
Change in velocity, _ v _ = v _ 2 _ v _ 1 = ( 40 j ^ _ 30 i ^ )
_ | _ v _ | = | 40 j ^ _ 30 i ^ | = 50 m / s
Average acceleration, a _ a v = c h a n g e i n v e l o c i t y T i m e i n t e r v a l
a _ a v = v _ 2 _ v _ 1 _ t = _ v _ _ t
| a _ a v | = | _ v _ | _ t = 50 m / s 10 s = 5 m / s 2
