Question

A force of 5N gives acceleration of 20ms^2 . find its mass *​

Answer 1

Answer:

a force of 5n gives acceleration of 20 ms^2 and its mass equals to 0.25

Answer 2

Answer:

A force of 5N gives a mass M1 an acceleration of 10 m/s2 and a mass M2 an acceleration of 20 m/s2. What acceleration would it give if both masses were tied together?

Long-term goals or a short-term goals, aim to meet them all.

Using Newton's second law,

F = m a

5 = M1 × 10

M1 = 5/10 = 0.5 kg

And

5 = M2 × 20

M2 = 5/20 = 0.25 kg

Total mass = 0.5 + 0.25 = 0.75 kg

Now as per question,

Let common acceleration is a,

F = (M1 +M2) ×a

5 = 0.75 × a

a = 5/0.75 =500/75 = 6.67 m/s²
