Question

Starting from rest the acceleration of a particle is
a = 2(t-1). The velocity of the particle at t= 5 s
is :-
15 m/s
25 m/s
(3) 5 m/s
(4) None of these​

Answer 1

Answer:

15m/s

Explanation:

Answer 2

Answer:

15 m/s

Explanation:

integrate acceleration to get velocity

integration of 2(t-1) is t²-2t = v

substitute t = 5

5²-2(5)

25-10

15
