Answer 1

B

Explanation:

So in this question, we have two forces and two velocities. We're asked to find the second velocity. From what we know

F₁ = 16N

V₁ = 2m/s

F₂ = 10N

V₂ = ?

Solution

when F₁ was 16N, V₁ was 2m/s. All that's left is to find the second velocity:

16N = 2m/s

10N = V₂

⇒ V₂ =
`(2 m/s * 10N)/(16N)`

=
`(20m/s)/(16)`

= 1.25 m/s

So now when we compare V₁ and V₂, we should get the answer

`(V1)/(V2) = (2m/s)/(1.25m/s)` = 1.6

V₁ is 1.6 bigger than V₂. This means the speed will decrease
