The net force is the centripetal force is 3.56 N.
F1= 3N
F2 = m v²/r
F 2= 0.150 kg*(2.8 m/s)^2/0.75 m
F2= 0.56N
Net force = F1+F2=3N+0.56N= 3.56 N.
As an object moves, the centripetal force pulls or pushes it towards the center of a circle, generating angular or circular motion. The force of tension on the rope pushes the object towards the center while spinning a ball on a string or twirling a lasso.
Centripetal force is described as the force acting on a body traveling in a circular route that is directed toward the body's center. The name is derived from the Latin words centrum, which means "center," and petere, which means "to seek." The centripetal force is the center-seeking force.

Answer:
A. 0.01 [kg] mass moving at 200 [m/s]
Explanation:
Momentum is defined as the product of mass by Velocity.
where:
m = mass [kg]
v = velocity [m/s]
<u>For the case A</u>
<u /><u />
If we perform this same operation with the values of mass and velocity we see that the momentums will be greater than 2 [kg*m/s], therefore the lowest momentum is achieved with the values in case A.
G= 9.8m/s^2 =
Well, think about the fall times and calculate the equation and then you will be able to solve G= 9.8m/s^2
I think G= gravity (I haven't learned this yet :P)
So gravity = 9.8m ( m = variable)
/s^2 (/= division) (s^2 =1 S(2)
(2 as power)
So if you set this up you will come up with[Gravity 9.8 multiplied by m divided by 1 multiplied by S(2)
I have never done something like this before so hope I got it right :)
