Question

An object has an acceleration of 12.0 m/s/s. If the net forcewas doubled and the mass was one-third the original value,then the new acceleration would be m/s/s.

Answer 1

By Newton's second law we have:

`a=(F)/(m)`

From the original mass, force an acceleration we have:

`(F)/(m)=12`

Now if we doubled the force and take a third of the mass we would have:

`(2F)/((1)/(3)m)=(2)/((1)/(3))\cdot(F)/(m)=6\cdot(12)=72`

Therefore the acceleration in this case would be 72 meters per second per second.
