2. launch the ball from a readily identifiable and repeatable point near the top of the inclined ramp.notice where it hits the floor.
3.Tape a piece of carbon paper to the floor around where the ball landed. launch the ball five times from the same place as before and verify that the ball lands in the virtually the same place each time.
4. Determine the height of the bottom of the ball when it launches, and how far out from the table's edge it lands.
Height h=93.7cm. How far from the edge of the table x=72.5cm.
5.Dteremine the launch speed of the ball from your measurments. sketch the dimensions clearly and show your calculation.
known g=9.8m/s^2
vertical: (1/2)gt^2= h => t=0.437s
horizontal: vt=x => v= 1.658m/s
6.imagine attaching an inclined board at the edge of the lab table such that now the, launched at the same spot as before, will strike the board a distance d along the board. Derive an sxpression that would allow you to determine the value of ad given that you know v0 and the angle.
7.Place a board such that it touches the end of the lab table and the floor. Put a heavy mass on the floor at the foot of the board and use duct tape to fix the mass in place. attach a piese of carbon paper to your board such that it " surrounds" the spot where you expect your ball to land. Make appropriate measurements to determine the angle of board. Then run the experiment, launching your ball five times from the same spot.
the angle between the board and horizontal is measured as α =48 degree.
tanα=H/X
H=(1/2)gt^2
X=v0t
=> t= 0.3758s
=>X=0.623m
cosα=X/d
=> d=0.93m
8.Determine the experimental value of your landing distances d and report your experimental value as d +_ σ
d+_0.03m
9.Compare your experimental and theoretical values for d. Comment on soures of uncetainty or error in the experiment.
