Question

two cars having masses in the ratio4:5, accelerate in the ratio 2:3 . find the ratio of force on each of them.​

Answer 1

Explanation:

Ratio of masses of cars= 4:5=4/5

Ratio of acceleration of cars= 2:3=2/3

since, force= mass*acceleration

Therefore,

ratio of force exerted = (4/5)*(2/3)= (4*2)/(5*3)=8/15

Ans: The ratio of force exerted by the cars is 8:15.

Answer 2

Answer:

SOLUTION

Let the masses be m1 and m2, accelerations be a1 and a2 & forces be f1 and f2.

We know that,

Force = Mass * Acceleration

So,

f1/f2 = m1/m2 * a1/a2

= 4/5 * 2/3

= 4 * 2 / 5 * 3

= 8 / 15

= 8 : 15 Ans.

Ans.) The ratio of forces exerted by each of them is 8 : 15.
