Question

1. What is the known value of the x- and y- components of the acceleration of the ball due to gravity?

ax = ? and ay = ?

2. Calculate for each

3. Take the data from the BEST TRIAL RUN at put theh into the table

4. Write these equations and include values that are given from the BEST TRIAL RUN

horizontal position: x(t) ?

horizontal velocity Vx(t) ?

vertical posotion y(t) ?

vertical velocity Vy(t) ?

Vertical velocity as a function posotion Vy2 (y) ?

4. Using these equations and data above fing how high your ball went in your best trial as well as magnitude and direction of its final velocity ( velocity just before hitting the ground )

EXP # Release height Time in air Horizontal distance traveled 1. 1 meter 2.3 sec 6.6 meters 2. 1 meter 1.5 sec 4.5 meters 3. 1 meter 1.36 sec 5.3 meters V0

Explanation / Answer

Ans:-

1] t= 1.72 , x= 5.47m, y=n1m

Using kinematical equation

X= V0t +1/2*axt^2

5.47 = 0.5* ax *1.72^2

ax= 3.7m/s^2

y= V0t +1/2*ayt^2

1= 0.5*ay*(1.72)2

ay = 0.68m/s^2

Vox                        voy                         |Vo|                     

2.87m/s                0.44m/s                2.9m/s                  8.72

3m/s                      0.67m/s                3.07m/s                12.59

3.9m/s                  0.74m/s                3.97m/s                10.74

Y             t              x              vox         voy         |Vo|     

1              1.36        5.3          3.9          0.74        3.97        10.74

4]

X(t) = 5.3 +3.9t +1/2*at^2

Vx(t) = 3.9 +at

Y(t) = 1+0.74t +1/2 *at^2

Vy(t) = 0.74 +at
