Question

Two car having masses 4:5aceelerated in the ratio 2:3 . Find the ratio of forces exerted by each of them

Answer 1

8 : 15

Explanation:

m1 = 4x kg

m2 = 5x kg

a1 = 2y m/s²

a2 = 3y m/s²

F1 = m1 × a1 = (4x)×(2y) = 8xy N

F2 = m2 × a2 = (5x)×(3y) = 15xy N

Ratio = F1 : F2 = 8xy : 15xy = 8:15

Hope It Helps ;)
