Question

Find the force which can be applied on a box which has a mass (9a-10b) Kg to accelerate in (9a + 10b) m/s^2.
Hint- to find the force the equation of force = Force x Acceleration.

(Please answer it correctly)

Answer 1

Answer:

By second law of motion we have the formula as

Force = mass × acceleration

Given Force 1=1×10=10 Newton

Given Force 2=2×4=8 Newton

Hence, force 1 is greater than force 2.

SI unit of force is Newton. 1kg=nearly 9.8N

Answer 2

Step-by-step explanation:

as smilpy , it will be multiplication therefore F = ma

so , (9a-10b) x (9a+10b) = 81a^2 - 100b^2 N
