I'm not sure what you mean, are you talking about inertia? i know I=1/3*M*L squared for the beam and Torque= I*angular acceleration

I'm still not getting the right answer and the only equations i can think of using are the ones i already tried.

I was using the forces from the weight of the box and bar and l also used the angle. Don't i need a length to use torque?

Ive tried tension of rope =1320cos50+1960*9.8 Vertical force= 1320sin30+1960*9.8 Horizontal force= 1320cos30+1960*9.8

Can you clarify a little more?

Homework Statement A 1320-N uniform beam is attached to a vertical wall at one end and is supported by a cable at the other end. A 1960-N crate hangs from the far end of the beam. Using the data shown in the figure, find (a) the magnitude of the tension in the wire and the magnitudes of the...

For some reason i get -611 for the velocity of the bullet, am i doing my algebra wrong? Vb=(Vb_before/VB_after)-MB When i solve for just the second block it get Mb*Vb_before/MB and i get 1.26 which is not the right answer

So do i need to figure out the velocity of the bullet after it goes through the first block, then use that to find the velocity of the second block? And do i use MbVb+MBVB=MbfVbf+MBfVBf b= bullet, B=block, f= final

Homework Statement A 5.39-g bullet is moving horizontally with a velocity of +354 m/s, where the sign + indicates that it is moving to the right (see part a of the drawing). The bullet is approaching two blocks resting on a horizontal frictionless surface. Air resistance is negligible. The...

Converting to m worked thanks for all your help.

Still didn't work and i have only one more chance to get it right, so if anyone else knows what I'm doing wrong i would appreciate it

Homework Statement A bicyclist rides 1.32 km due east, while the resistive force from the air has a magnitude of 6.12 N and points due west. The rider then turns around and rides 1.32 km due west, back to her starting point. The resistive force from the air on the return trip has a magnitude...
