Question

What would be the force required to produce an acceleration of 2m/s2 in a body of mass 12kg? What would be the acceleration if the force were doubled?

Answer 1

Answer:

24 kg m/s2

Explanation:

force = mass * acceleration = 12 * 2 = 24 kg m/s2

If the force is doubled then the acceleration will also be doubled because acceleration is directly proportional to force

Answer 2

$\small{\underline{\sf{\orange{Given:\rightarrow}}}}$

• $\sf{ Acceleration \ [a] = 2m/s^2 }$

• $\sf{Mass \ [m] = 12kg }$

$\small{\underline{\sf{\red{SoLution:\rightarrow}}}}$

• What would be the force required to produce an acceleration of 2m/s²in a body of mass 12kg?

$\sf{\implies F=ma }$

$\sf{\implies F= 12\times 2= 24N }$

$\boxed{\sf{F= 24N}}$

• What would be the acceleration if the force were doubled?

Here force is doubled so,

$\sf{F= 2\times 24 = 48N}$

Putting value of F and m in F=ma, we get

$\sf{\implies 48 = 12 \times a}$

$\boxed{\sf{\implies a= 4m/s^2 }}$
