Answer:
6.28 m/s.
Explanation:
Given that,
The mass of the object, m = 0.2 kg
The radius of the circle, r = 0.5 m
It takes the object 0.500 s to complete one revolution.
We need to find the translational speed of the object. Let it is v. We know that,
So, the transalational speed of the object is 6.28 m/s.
Answer: Question 10: I believe the answer is C, hope this helps!
Explanation:
60mph= 26.8224 m/s
accelerationn= final velocity-initial velocity/time
A non-contact force is a force which acts on an object without coming physically in contact with it. In contrast a contact force is a force which acts on an object coming physically in contact with it. ...
