An empty truck wieght 4000N.its engine can produce a maximum acceleration 1m/s square .if truck is loaded with 2000N,find the maximum acceleration the engine can produce.i want watch video of this question.physic

F = m a
F = (4000/g)(1) = 4000/g Newtons

same F but now mass is 6000/g
4000/g = (6000/g) a
a = 4/6 = .67 m/s^2
