The velocity of a particle at an instant is 10 ms⁻¹.After 3 s its velocity will become 16 ms⁻¹.The velocity at 2 s before the given instant, will be
Options
(a) 6 ms⁻¹
(b) 4 ms⁻¹
(c) 2 ms⁻¹
(d) 1 ms⁻¹
Correct Answer:
6 ms⁻¹
Explanation:
Given: v=16 ms⁻¹;u=10 ms⁻¹;t= 3s; a=?
v=u+at
16=10+a(3)
3a=16-10⇒3a=6⇒a=2 ms⁻²
before 2 s,⇒10=u+2×2⇒u=6 ms⁻¹.
