A bicycle takes 8.0 seconds to accelerate at a constant rate from rest to a speed of 4.0 m/s. If the mass of the bicycle and rider together is 85 kg, what is the net force acting on the bicycle? (Hint: first, calculate acceleration) Acceleration = Fnet =

42.5km/s^2

Explanation:

Fnet=m⋅a

We know that

Here,  

v=4m/s,  u=0m/s,  t=8s

Also, we have  m=85kg

Fnet=85  kg⋅0.5  m/s2=42.5N

Acceleration = (change in speed) / (time for the change)

Acceleration = (4 m/s) / (8 seconds)

Acceleration = 0.5 m/s²

Force = (mass) x (acceleration)

Force = (85 kg) x (0.5 m/s²)

Force = 42.5 Newtons

Explanation:

We would need to use Newton's second law ofmotion, which states that-

We know that,

Here,v = 4 m/s, u = 0 m/s, t = 8 s

Also, we have

m = 85 kg

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!

your answer is, orbit around the nucleus
