The force needed in this situation is 15 newtons. The formula appears below.
Force = (mass) times (acceleration)
F = 3 x 5 = 15 newtons

Increasing the number of pulleys divides the force required to lift up a heavy object; increasing the number of pulleys decreases the force needed by the person (or motor) pulling the first end of the pulley system. However, it is important to know that it does not affect the total work needed to lift up the object. As the force is decreased, the distance of rope needed increases to compensate for a conserved amount of work required for the load to be lifted.
From Newton's second law, F=m*a (net force is the product of mass and acceleration).The mass here is 45 kg, and the acceleration is 2m/s2.Multiply the two together.
From F=m*a, acceleration = force / mass Since mass is in the denominator, it would follow that the less mass there is, the greater the acceleration, force being equal. Although an average motorcycle has, perhaps, half the horsepower of a medium size car, it has MUCH less mass.
F = M A = (13) x (25) = 325 newtons
Force = mass * acceleration Force = (3 kg)(5 m/s2) = 15 Newtons ===============( takes about 1 Newton to press a doorbell )
F = ma(Force = Mass * Acceleration)F = (3) * (5)F = 15 N(15 Newtons)

You twice it.
Force = mass * acceleration Force = (4kg + 46kg) * 3 m/s2 Force = 50kg * 3 m/s2 Force = 150 kg*m/s2 or Force = 150 Newtons
90 n is needed to accelerate your body at a rate of 2 if you weigh 45 kg.
Force = Mass* Acceleration = 66 Kg * 2 m/second = 132 Kg meters per second per second = 132 Newtons.
