A body weighing 10 kg is acted upon by two forces directed along one straight line.

A body weighing 10 kg is acted upon by two forces directed along one straight line. The body moves with an acceleration of 2 m / s². The modulus of one mil is 50 N. What is the modulus of the other force?

Newton’s second law – F = ma. F_ {1} = 50H, F_ {2} = x m = 10kg a = 2m / c ^ {2}. Solution: m * a = 2 * 10 = 20H. 50 \ neq 20. Then 50-20 = 30 50-30 = 20, 20 = 20, the equality is fulfilled. This means that the second force is 30N, and the resultant is 20N, which is equal to the product of mass and acceleration.
