Problem 1

Description

A red ball slides off a table as shown in the animation (position is in meters and time is in seconds). Ignore air friction. The ball hits the other table after moving a distance x. (Remember to click and drag to find x and y.)

Question 1
What is Vx just before the collision ? To find this quantity, please measure the ball's change in x four times  and take the average of the four measurements. Assume the measurements are in meters and are  precise to the 1/100 place.  Fill in the table below  with the measurements

first x second x difference
     
     
     
     
    average 
difference
     

Vx  = ____________________________

Question 2
What is Vy just before the collision ?  Assume g = 9.80 m/s2 ( 3 sig.fig.) 
Question 3
What is the speed just before the collision? Use the Pythagorean Theorem.
Question 4
What  is the magnitude of the angle that the velocity vector makes with the horizontal just before the collision? Use trigonometry.
