Question

a body moving with an initial velocity 4î +3j^ and after sometime
an acceleration of 4i^+3i^is applied. What is the final velocity
after
one
second?


​

Answer 1

Explanation:

t= 1

v= ?

u = 4 i + 3j

|u| = root 4^2 + 3^2

u (magnitude)= 5m/s

similarly

a = 5 m/s^2

v= u+a×t

v = 5 + 5×1

v =10m/s
