Solution
Initial mass = 2500 Kg
Initial acceleration = 1.5 m/s2
Net force = 3750 N
Final mass = 4000 Kg
Since the force remains the same, the final acceleration = F/m = 3750/4000 = 0.9375 m/s2
Initial mass = 2500 Kg
Initial acceleration = 1.5 m/s2
Net force = 3750 N
Final mass = 4000 Kg
Since the force remains the same, the final acceleration = F/m = 3750/4000 = 0.9375 m/s2
