Question

A force F1 acting on a 2kg body produces acceleration of 2.5 m/s square.Another force F2 acting on a 5 kg produces an acceleration of 2 m/s square.Find the ratio F2/F2(HINT formula from newton's 2nd law)

Answer 1

Hello friend !!!!

Here's the answer you are looking for

Newton's second law states the rate of change of momentum is directly proportional to the unbalanced force applied.
From which we get, F = ma

In 1st case

mass, m1 = 2kg
and
acceleration, a1 = 2.5 m/s²

So, F1 = 2 × 2.5 = 5N

In 2nd case

m2 = 5kg
and
a2 = 2m/s²

So, F2 = 5 × 2 = 10N

Therefore, F1 / F2 = 5/10 = 1/2

Answer 2

Answer:

F=ma

In 1st case

mass , m1 is 2kg

acceleration , a1 is 2.5m/s square

F1=2*2.5=5N

In 2nd case

m2 is 5kg

a2 is 2 m/s^2

F2=5*2=10 N

F1/F2=10/5=1/2 is 1 : 2
