again, thanks for everyone's help on the other problems, here is one last question. For part b.) the answer seemed to easy, and I wasn't sure if I was doing it correctly! here's the problem
In a laboratory experiment, you wish to determine the initial speed of a dart just after it leaves a dart gun. The dart, of mass m, is fired with the gun very close to a wooden block of mass, M., whichhangs from a cord of length L, and negligible mass. Assume the size of the clock is negligible compared to L, and the dart is moving horizontally when it hits the left side of the block at its center and becomes embedded init. The block swings up to a maximum angle (theta max) from the vertical. Express your answers to the following in terms of m, Mo, L, (theta max), and g.
b.) The dart and block subsequently swing as a pendulum, Determine the tnesion in the cord when it returns to the lowest point of the swing.
I set up a free body diagram and got T =mg It just seemed to easy- so my final answer was T = (m + Mo)g
thanks for any help!
