Answer: The ball would exert and equal force on the astronaut in the opposite direction. Both would move away from each other in a straight path. Hope this helps!
You are dealing with pulleys?
can be done with addition of the two equations to eliminate T.
+
=
we can cancel m₁ by dividing both sides by it, assuming mass is not zero
a₂ = 6.125 m/s² ( do significant digits if you need to)
Explanation:
The force between two charges is given by :
k is electrostatic constant
r is distance between charges
The force between charges is directly proportional to the product of charges and inversely proportional to the square of the distance between them.
The correct answer is C) towards the center of the circle.
Although the object is moving at a constant speed it is constantly accelerating due to the constant change in direction as it describes the circular path. This causes a constant change in velocity as velocity is a vector quantity.
For the object to maintain the circular path there has to be centripetal force acting on the object and this centripetal force is directed towards the center of the circle.
50π m ≈ 157 m
Explanation:
100 rev/min (2π rad/rev) / (60 sec/min) = 3⅓π rad/s
d = ωrt = 3⅓π(0.50)(30) = 50π m ≈ 157 m
