Answer:
v = 23.87 m/s
Explanation:
Given that,
The radius of wheels, r = 0.380 m
The wheels rotate once every 0.1 s
We need to find the linear velocity of the wheels. The linear velocity of a wheel is given by :
So, the required linear velocity of the wheel is equal to 23.87 m/s.
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.
