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.
 
The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...
Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?
Thread 'Beam on an inclined plane'
Hello! I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below. Here is how I wrote the condition of equilibrium forces: $$ \begin{cases} F_{g\parallel}=F_{t1}+F_{t2}, \\ F_{g\perp}=F_{r1}+F_{r2} \end{cases}. $$ On the other hand...
