Answer:
Hey
I have no idea when YOUR assignment is due.
Newtons 1rst law:
An object that has constant motion will remain at that speed unless acted on by an external force.
Newtons 2nd law:
F=ma (force=mass*acceleration)
Newtons 3rd law:
when a force is applied to an object, there will be an opposite but equal reaction.
Acceleration:
How much your speed increases/decreases per unit of time.
I wrote all that^
M is 3kg
r is 2m
v is 6m/s
Fc = mv^2 / r
Fc = (3x6^2)/2 =54
a = v^2/r
a = 6^2 /2 = 18
I'm pretty sure it's B
I hope that helps
