the force needed is 8.89m/s2 .
F = ma = 1250 x 40 = 50,000 Newtons
F=ma, so=70*4.2=294NAnd acceleration has units of ms-2
70 kg x4.2 m/s 140 +2800 294.0 m/s
90 n is needed to accelerate your body at a rate of 2 if you weigh 45 kg.

F=ma, Force=(mass)(Accleration), (3)(1250)-(3)(200)= 3,150 Newtons
Force = mass x acceleration = 70 x 4.2 = 294 Newtons
F=ma, so=70*4.2=294NAnd acceleration has units of ms-2
The force needed to accelerate an object at some rate is proportional to the object's mass.The object may be moved by as small a force as you want. It just won't accelerate at a very high rate.
70 kg x4.2 m/s 140 +2800 294.0 m/s
90 n is needed to accelerate your body at a rate of 2 if you weigh 45 kg.
An increase in applied force will cause the object to accelerate.

Newton's 2nd law of motion states that F=ma Therefore, the force required is just the mass X the acceleration so 70 X 4.2 which equals a force of: 294 Newtons
