Question

The velocity of a particle increases linearly with time i.e. v=kt, where k = 2 m/s. The distance covered in first three second will be
(A) 12 m
(B) 6 m
(C) 9 m
(D) 18 m​

Answer 1

Answer:

D 18m

Explanation:

from the given equation

at t=3 sec

v= 2×3= 6 m/s

distance d = v * t

= 6*3

d = 18 m

Answer 2

Answer : 9m

• Always Integrate when given (first x seconds)

• Bring the to integrate (here x) on one side from the equation. e.g - v = dx/dt -----> v dt = dx
