1. In this lab we will find the velocity of a ball firing into a ball going up a theta.
2. In this lab we utilized a ball . A pendulum mechanism which when firing a ball into the block will go up an angle theta. the ball stays inside which will make it into a inelastic collision. A slow motion video will be posted below on how the mechanism works.
3. We did 3 trials of shooting the ball. Getting 3 thetas and using the average. The mass of the block was 84g and the ball was 8g both with a +-.1 in uncertainty
L up in the work is the length of the string, being 21 cm. When plugging in the data our V initial for the ball come out to be around 6m/s
After this we decided to do the second of the lab for fun which is if the ball is shot from the table how far away will it land. we measured the height of the table, distance inside the table where the ball will be shooting from and with simple kinematics ( Y direction to see when it hits the floor then use the time to find the x distance) the distance away from the table would be 2.44m and the total distance traveled by the ball would be 2.7 m work will be posted below.
In conclusion, in this lab we use the conservation of momentum and the conservation of energy to find the velocity initial of the ball, and therefore use a few measurements to find the distance the ball would travel. This ballistic pendulum lab was great to show how momentum and energy are conserved. Cheers.
