What is the angle made by the ramp and the floor in a bowling ball problem?

AI Thread Summary
To determine the angle between the ramp and the floor in the bowling ball problem, one must first calculate the acceleration of the ball using the given time of 5.0243 seconds and the ramp's length of 8.5 meters. A free body diagram is essential for visualizing the forces acting on the ball, which will help apply Newton's second law. The acceleration due to gravity is provided as 9.81 m/s², which is crucial for these calculations. The angle can then be derived from the relationship between the ramp's height and base length, using trigonometric functions. Understanding these concepts will lead to the solution of the angle formed at the bottom of the ramp.

I'm having a lot of trouble with the problem for my AP Physics Class

There is a bowling ball traveling down a ramp. The ball starts resting. The ramp's hypotenuse is 8.5 meters long and is across from a 90 degree angle. The average time it takes the ball to travel down the ramp is about 5.0243 seconds. We can assume a=9.81m/s^2. What is the angle horizontal made at the bottom of the ramp and the floor? Thanks

You need to find the acceleration of the ball. Draw a free body diagram and use Newton's second law.
 

Thread 'Is calling fictitious forces not real just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
