Purpose
To use the understanding of projectile motion to predict the impact point of a ball on an inclined board
Procedure
Set up as picture
Once the apparatus has been set up, we launched the steel ball from an identifiable point on the v-channel to see where it would land. We placed the carbon paper at the impact point on the floor and launched the ball five more times to get a more accurate distance of how far out from the tables edge the ball landed. We hung a plumb bob as well to get even more accuracy. After observing the marks on the carbon paper we used a meter stick to measure the distance from the edge of the table to the impact point.
Data
We measured the angel as 48 degree
and height of the point where ball free fall as 0.9638m and vertical travel distance as 0.6550m
Results/Analysis
After finding the launch velocity of the ball, we needed to find out where the ball would land on a different height. And the picture is about calculated result of the landing point at a new height.
Conclusion
The ball landed exactly where we expected it to land which was 75.21cm away from the initial point of the ramp. Our experiment was very successful although we had a little bit of uncertainly.
