A small projectile is fired vertically downward into a fluid medium with an initial velocity of 60 m/s. Due to the drag resistan
BaLLatris [955]

Answer:

Velocity after 4 seconds becomes 58.4m/s

Explanation:

By definition of acceleration we have

a=\frac{dv}{dt}

It is given in our case that a = -0.4m/s^{2}

Thus we have

\frac{dv}{dt}=-0.4m/s^{2}\\ \\\\dv=-0.4dt\\\\Upon Integrating \\\\\int_{60}^{V_{f}}dv=\int_{0}^{4s}(-.4)dt

Thus solving we get

V_{f}-60=(-0.4)(4-0)\\ \\V_{f}=-1.6+60\\ \\V_{f}=58.4m/s
