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//

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
