Q: One horse pulls with X newton force a mass of 800 kg along a horizontal road at constant speed. 3 horses, each pulling with a force of X newton gives the cart 0.8 ms*2 acceleration. Find the time it would take 2 horses to increase the speed of the cart from 2 ms to 5 ms ? Given that each force pulls with X newton and the resistance force to the motion has same value for the three times.
answer is 7.5 sec.
