Question

For question 46 use table 1.1 and 1.2

46. Four students are trying to figure out how gravity affects the acceleration of an object. They start off by throwing a 55.88g tennis ball and a 4.22g Ping pong ball from a height of 5.7 meters. Each student takes ten throws for the tennis ball and the ping pong ball. Calculate using the data in table 1.1 and 1.2 to find gravity ignoring the friction present in the air and include a table with all the data from each student combined showing all the calculation. Calculate all the values needed for the best fit line equation for the tennis ball and the ping pong ball, and then find the equation of the line based on your work.

Explanation / Answer

Since that doesn't change anywhere on Earth, the only thing that changes the force of gravity is the mass of the object (which is a lot like how much it weighs). Here, if you drop two balls at the same time, you'd see that they both accelerate exactly the same way, no matter how much either one weight

                       In experimentally one of the acceleration due to gravity equation for free fall can be used for calculating acceleration due to gravity .The equation is

                     h=(1/2)gt^2

then              g=2h/t^2

An object of considerable weight (because the air resistance can be neglected), be dropped from fairly tall building whose height is accurately measured. The observer at the top of the building switches on a digital timer at the same instant he drops the object. The observer at ground level switches off the same timer when the object hits the ground and records the time of fall. Plugging the values of h and t, the acceleration due to gravity can be calculated. The experiment may be conducted for a few times and the mean of reading may taken.

Here , For student1 acceleration due to gravity for tennis ball, by using equation ,

t=1.12s

                      g1=2x5.7/(1.12^2 sec)=9.08m/sec

t=1.16s

                      g2=2x5.7/(1.16^2sec)=8.47m/sec

t=1.13s

                      g3=2x5.7(1.13^2sec)=6.7m/sec

Now in ping pong ball

t1=1.25sec

              g1=2x5.7(1.25^2sec)=7.296m/sec

t2=1.3sec

            g2=2x5.7(1.3^2)=6.74m/sec

t3=1.29sec

           g3=2x5.7(1.29^2)=6.85m/sec

Above equation can be used for all calculations.
