Answer:

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:

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
