I derived the angle of reflection for all four combinations of the directions of u_x and u_y and angle of inclination. However, I have a new problem now: If we consider the case of the first fall (free-fall under gravity) of any ball , it can correspond to the 'u' in the 3rd or 4th quadrant...

I did read it. I just happened to have posted the message before I saw yours. Thanks

I will illustrate my difficulty more specifically with an example. I've observed that for an incline (θ<90) and vector 'u' along the 4th quadrant, the ball can rebound off the plane or bounce off further in the same direction of motion depending on the orientation of the incline. Therefore in...

So how do I calculate the angle of reflection with respect to the ground plane (not w.r.t to the incline). I'm reluctant to align the coordinate system along the incline because I do not understand how would the axes be if the angle of inclination of the plane is greater than 90 or negative...

I believe this holds when the coordinate system is along the inclined surface. Does it also hold true if the coordinate system is along the ground plane ?

1. Hi, I'm a computer engineering graduate. I'm developing a computer game similar to Soundrop (Apple). The situation is: balls fall vertically down under the effect of gravity. There are various inclined planes in the frame (of known angle of inclination). There could be multiple...

I'm planning to design a PIR motion sensor. I wanted to know if I can use ordinary class-A amplifiers to amplify the output of the sensor which will be given to the alarm circuit. The transistor I'm planning to use is BC-547

In labs we often use a potentiometer to determine the i/p & o/p impedance of an amplifier. But I've failed to understand why this procedure is adopted; can anyone please help me on this ?

guys if u need more clarification abt the question please let me know

1. The problem statement: A leaky capacitor, Zc =74.5 ohm is in series with a coil Z coil = 40 ohm and a resistor R=50 ohm. When a voltage V=200V is applied I=2.5A and the p.d across R and Z coil is combined is 194V. Find the loss in the capacitor. Homework Equations Z=(R^2...

thanks
