Question

A 40 kg bike traveling down the road has a negative acceleration. What is true of the force? A. It is positive B. It doesn't exist C. It is negative D. It is zero

Help me pls.

Answer 1

C. It is negative

Step-by-step explanation:

Per Newton's second law, the net force is the mass times the acceleration:

∑F = ma

If the acceleration is negative, the net force is negative.

Answer 2

C. It is negative

Step-by-step explanation:

As we know that mass of the bike is given as

m = 40 kg

now we know by Newton's law of motion

`F = ma`

here we know that

m = mass of the bike

a = acceleration of the bike

so here we will have

`F = 40 (a )`

now if the acceleration of the bike is in negative direction

then we will get a negative force on it as per above formula

so correct answer will be

C. It is negative
