Answer:
Dynamometer
Explanation:
We might want to use a system that calculates weight, but we would need to change it for the task, depends entirely on the task. Let 's imagine we're taking a scale to test people's weight, and you're moving it between something that moves the box and the box that are being moved, because when we push you will see the scale calculate distance. Then force until the container continues to flow.
The motorized toy boat experiences a net force of 0 N between 4 s and 8 s.
The motorized toy boat moves at 8 m/s (u) at 4 s and at 8 m/s (v) at 8 s. We can calculate the acceleration (a) in that period using the following kinematic expression.

The object with a mass (m) of 2.0 kg experiences an acceleration of 0 m/s². We can calculate the net force (F) in that period using Newton's second law of motion.

Answer:
The centripetal force will be 1/2 as big as it was. (option c)
Explanation:
Recall that centripetal force (
) is defined as:
where "v" is the tangential velocity of the object in circular motion, "r" is the radius of rotation and "m" is the object's mass.
So if we start with such formula with a given mass, radius, and tangential velocity, and then we move to a situation where everything stays the same except for the radius which doubles, then the new centripetal force (
) will be given by: 
and this is half (1/2) of the original force:

which is expressed by option "c" of the provided list.
Answer:
The angular displacement would be 6 Pi radians or 1080 degrees.
Explanation:
Every individual rotation is 2 Pi (this applies to anything regardless of radius).
Since there are three rotations you are going to multiply 2 Pi by 3.
This will give you 6 Pi which you can convert to equal 1080 degrees (1 Pi = 180 degrees).
