16. A certain force applied to a 2 kg mass accelerates the mass at 3 m/sHow much acceleration will the same force produce on a 4 kg mass?

1.5  m/s²

Explanation:

Force = mass X acceleration

OR, you could rearrange the equation to see that

Force divided by Mass equals Acceleration.

F

 =  A    So if you are doubling the Mass, the Acceleration would

M              get cut in half.

As an example:    if F=4 and M=1 the acceleration is 4

                             if F=4 but M=2, the acceleration is now 2

So the answer will be half of 3 which is 1.5

its answer is 1.5 m/s².

Explanation:

F =m × a

F= 2×3

F = 6

In the second case, force is given  and mass is also given. So we have to find the acceleration by applying the same formula

F = m× a

6 =4 × a

6÷4 = a

1.5 m/s² = a
