Question

is
A body moving with an initial velocity of 5 ms- attains a velocity of 15 ms in 3 s. Then the displace​

Answer 1

Explanation:

Initial Velocity (u) = 5m/s

Final Velocity (v) = 15 m/s

Time taken (t) = 3 sec

Let acceleration of body be a

Using v = u + at

15 = 5 + a(3)

a = 10/3 m/s²

Now using s = ut + 1/2at²

s = (5)(3) + 1/2(10/3)(3)(3)

s = 15 + 15

s = 30m

So the displacement of the body is 30m.
