Calculating Energy Loss with Ballistic Pendulum

AI Thread Summary
Energy loss in a ballistic pendulum setup is calculated by comparing the initial kinetic energy of the projectile to the final gravitational potential energy after the collision. The initial kinetic energy is 0.929 J, while the final potential energy is 0.198 J, resulting in an energy loss of 0.731 J. This loss is attributed to factors such as friction, air resistance, and waste heat during the collision. The collision between the projectile and the pendulum is typically inelastic, meaning that kinetic energy is not conserved. Understanding these energy transformations is crucial for analyzing the efficiency of the ballistic pendulum.

Homework Statement


How was energy lost while using the ballistic pendulum?


Homework Equations


Initial KE= 1/2mb*Vb^2 = 0.929J
Final Potential graviational = (m+M)gh= 0.198J
Energy loss = 0.929J - 0.198J= 0.731J

The Attempt at a Solution


I think the answer is:
energy lost dues to friction (air resistance) and waste heat while using the ballistic pendulum.

is this correct? Please help? Thanks a lot in advance.

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'A bead-mass oscillatory system problem'

I can't figure out how to find the velocity of the particle at 37 degrees. Basically the bead moves with velocity towards right let's call it v1. The particle moves with some velocity v2. In frame of the bead, the particle is performing circular motion. So v of particle wrt bead would be perpendicular to the string. But how would I find the velocity of particle in ground frame? I tried using vectors to figure it out and the angle is coming out to be extremely long. One equation is by work...
