Question

This equation represents Newton's Second Law of Motion, F=ma. It shows the relationship of force, mass, and acceleration.

If the mass of an object is tripled, and the force acting on it is doubled, how will the object's acceleration be affected?

A. Acceleration will be six times the original value.
B. Acceleration will be one-half the original value.
C. Acceleration will be two times the original value.
D. Acceleration will be two-thirds the original value.

Answer 1

Will give medals and fan!

Answer 2

What do you think?

Answer 3

I thought it was b, i'm just checking my answers.

Answer 4

Try solving the F=ma for a and then modifying F and m.

Answer 5

If you plug in 350 for force, 75 for mass, 5 for acceleration and then do as told it would look like 700=225*3.111111111
2/3 of 5 is 3.333333
1/5 of 5 is 2.5.
Since 2/3 5 is closest, the answer would be A right?

Answer 6

D is correct because its two-thirds of initial acceleration

but A is clearly wrong because A says that new acc will be 6 times of original
and original acc is 5
6 times of 5 is 30 which is way more than the new acc which we calculated
