The time taken for the group of people to pull the car, giving it a velocity of 1.5 m/s is 3.75 s
Momentum is simply defined as the product of mass and velocity i.e
Momentum = mass × velocity
To answer the question given, we'll begin by calculating the change in momentum. This can be obtained as follow:
Mass = 1500 Kg
Initial velocity (u) = 0 m/s
Final velocity (v) = 1.5 m/s
<h3>Change in momentum =? </h3>
Change in momentum = m(v – u)
Change in momentum = 1500 (1.5 – 0)
Change in momentum = 1500 × 1.5
<h3>Change in momentum = 2250 Kg•m/s</h3>
Finally, we shall determine the time
Change in momentum = 2250 Kg•m/s
Force (F) = 600 N
<h3>Time (t) =? </h3>
Impulse = Ft = change in momentum
FT = change in momentum
600 × t = 2250
Divide both side by 600
t = 2250 / 600
<h3>t = 3.75 s</h3>
Thus, the time required is 3.75 s
