Aparticle is moving along a straight line through a fluid medium such that its speed is measured as v=(2t) m/s, where t is in seconds. if it is released from rest at s=0, determine its positions and acceleration when t=3 s.

2 m/s², 19.62 m

Explanation:

v = Final velocity = 2t

t = Time taken

u = Initial velocity

s = Displacement

a = Acceleration

From the equation of motion

The acceleration of the particle is 2 m/s²

at t = 3 seconds

The position at t = 3 seconds is 19.62 m
