What does this mean? Where did 66.1 degrees come from? What significance does it have? How am I supposed to "use" it?"and use the angle theta measured with respect to the vertical which is 66.1 degrees.
But the problem already gives the velocity at the top of the circle -- so you can solve easily for the velocity at any other part of the circle. What minimum velocity is it asking about?What minimum speed v is required to keep the ball moving in a circle?
The horizontal and vertical motions are independent. For this problem, just completely ignore the horizontal component. The 19.5 m/s is just a red herring!Originally posted by pringless
A particle of mass .349kg is shot from a point P, at height L = 97 m, with an inital velocity v having a horizontal component of v_x = 19.5 m/s. The particle rises to a maximum height of h = 22.5 m above P. Using conservation of energy, determine the vertical component of v at the inital position P.
If you're referring to the work done from the highest point in its motion, yes.Originally posted by pringless
to find the work done by the graviational force on the particle would i just be using mgh but with the total distance of L + h now?
The minimum speed required to keep a ball moving in a circle can be calculated using the formula v = √(r*g), where v is the minimum speed, r is the radius of the circle, and g is the acceleration due to gravity.
The minimum speed required to keep a ball moving in a circle is directly proportional to the radius of the circle. This means that as the radius increases, the minimum speed also increases. This is because a larger radius means a longer distance to travel in the same amount of time, requiring a higher speed.
Yes, the minimum speed required to keep a ball moving in a circle is usually much lower than the speed of light. In most cases, it is within the range of human capabilities. However, if the radius of the circle is extremely small, the minimum speed required may approach the speed of light.
The mass of the ball does not directly affect the minimum speed required to keep it moving in a circle. However, a heavier ball may require a higher speed to overcome the force of gravity and maintain a circular motion.
If the minimum required speed to keep a ball moving in a circle is not maintained, the ball will deviate from its circular path and either move outward or inward. This is due to the balance between the centripetal force (provided by the minimum speed) and the centrifugal force (pulling the ball away from the center of the circle).
