Hi I need help with the following question 1,2,3 and 4 (Analysis Questions Only)

Please use grade 12 physics method.

Make sure to add direction when necessary

And Round to the correct significant digits

Please, d o this for a great high rate :))

Procedure 1. Place the ruler on a shallow incline so that the top is propped on some solid surface (like a thick book) and the bottom of the incline is right at the edge of the desk. 2. Roll the ball down from the top of the inclined ruler. Measure the horizontal distance (:11) the ball travels before it hits the floor that is: the distance from the point of the oor immediately below where the ball leaves the average distance. Record this information in a table titled Table 1. 3. Measure the vertical height (bl) of the desk. 4. Measure the vertical height of the slotted ruler (.312: height above the desk}. 5. Now place a target ball on the desk so that when the rst ball rolls down the incline, it collides head on with the target ball. The target ball now becomes the projectile. Measure {$2. the distance from the desk that the target ball strikes the floor. Repeat this measurement ten times and calculate the average distance. Record this information in a table titled Table 2. Note: ball bearing must be traveling horizontally as it leaves the table. Note: ball bearing must be traveling horizontally as it leaves the table. Analysis Questions 1. Using the data from steps #2 and #3 and the projectile equations: calculate the horizontal velocity of the ball just before it leaves the table. 2. Using the data from step #4 and the velocity calculated in the previous question. compare the gravitational potential energy of the ball at the top of the incline. with the kinetic energy of the ball just before it leaves the table (you do not need to ltnovv the mass, just let it equal 111). Is the mechanical energy being consewed? Discuss. 3. Using the data from steps #3 and #5: determine the horizontal velocity of the target ball, just before it left the table. Using the value of velocity you just calculated, compare total momentum just before the collision with the total momentum after the collision (again let the masses of the balls be m). 4. Discuss the laws of mechanical energy conservation and momentum consewation. Then relate the laws to the various steps of this experiment
