The resultant force F = mass x acceleration.
Resultant force = (250N) - (20 x 9.81)N = 53.8 N.
Thus acceleration = 53.8 / 20 = 2.69 m/s^2.
At constant velocity, the resultant force = 0N.
Resultant force = (250N) - (20 x 9.81)N = 53.8 N.
Thus acceleration = 53.8 / 20 = 2.69 m/s^2.
At constant velocity, the resultant force = 0N.
