Question

A force 10N gives a mass m1 an acceleration of 10m/s² and a mass m2 an acceleration of 20m/s² what acceleration would it give if both masses are tied together ?​

Answer 1

Answer:

Using Newton's second law, F = m a 5 = M1 × 10 M1 = 5/10 = 0.5 kg And 5 = M2 × 20 M2

Answer 2

Case 1:-

Given:-

•Force(F)=10N

•Mass=m1

•Acceleration(a1)=10m/s²

To find:-

•Mass(m1)

Solution:-

By using Newton's 2nd law of motion,we get:-

=>F=m1a1

=>m1=F/a1

=>m1=10/10

=>m1=1kg

Case 2:-

Given:-

•Force(F)=10N

•Mass=m2

•Acceleration(a2)=20m/s²

To find:-

•Mass(m2)

Solution:-

=>F=m2a2

=>m2=F/a2

=>m2=10/20

=>m2=0.5kg

Now,for combined masses(m1+m2)

=>F=(m1+m2)a

=>a=F/(m1+m2)

=>a=10/(1+0.5)

=>a=10/1.5

=>a=6.67m/s²

Thus,when both the masses are tied together,the acceleration is 6.67m/s².
