Answer:
when the ball is at rest in his coach's hands.
Explanation:
The forces on the basketball are balanced when the basketball is not experiencing any acceleration. This happens when the ball is in his coach's hand: in fact, at that moment the ball is at rest, so it means that its acceleration is zero. According to Newton's second law, this also mean that the net force on the basketball is zero, so the forces on the ball are balanced:
where F is the net force, m is the mass of the ball and a is the acceleration.
Answer:The Atwood Machine is a device that demonstrates the basic principles of acceleration and dynamics. You'll mostly see Atwood machines in Physics laboratories and classrooms. It consists of two objects with different masses that hang vertically from a frictionless pulley that has a very small, negligible mass.
Explanation:
Explanation:
According to the general theory of relativity, spacetime curves due to the energy it contains. Since mass is a form of energy, "create" gravity. That is, gravity is the effect observed as a consequence of the curvature of spacetime. Therefore, gravity curves the path of light because it curves the space through which light passes.
Answer: Mental health and physical health are very closely connected. Mental health plays a major role in your ability to maintain good physical health. Mental illnesses, such as depression and anxiety, affect your ability to participate in healthy behaviors.
Explanation: Hope this helped. Have a great day!!!!
Explanation:
The efficiency of a machine is 70% means 30% of the applied force is wasted in overcoming friction and 70% of the applied force is used to do the work
