For a moving object, the force acting on the object varies directly with the object's acceleration. When a force of 40 N acts on a certain object, the acceleration of the object is 8 /ms2. If the acceleration of the object becomes 10 /ms2, what is the force?

50N

Step-by-step explanation:

Force Is directly proportional to a

F = ka where k is constant of proportionality .when 40 is applied

F= ka

40 = k x 8

K = 40/8

K= 5

When acceleration increase

to 10m/s² with the same constant the force is;

F= ka

F = 5 × 10

F = 50N//

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5
