A climber of mass m is scaling the vertical wall of a mountain. His safety rope is made of nylon that, when stretched, behaves like a sping with a spring constant k. He stops to rest, but then accidentally slips and falls freely for a distance h before the rope runs out of slack. The rope then...

Oh, I understand about what you are saying, the velocity is different at different radi on the disk, so the acceleration would be changing too. So (A) makes sense as the answer, because the speed isn't the same at any point on disk, it is always changing. Hopefully this is the right answer...

Oh would it be (E)The angular accerlation is the same for any point on the disk. Wouldn't that be false because the acceleration closer to the point in the middle of the disk would be faster than the outsides rotational speed.

Homework Statement Which one of the following statements is NOT true for a rotating CD undergoing angular acceleration? A) The angular speed is the same at any point on the disk B) The lnear speed is the same at any point on the disk C) The angular accerlation is perpendicular to the...

Homework Statement A projectile mass (mass=0.20 kg) is fired at and embeds itself in a target (mass=2.50 kg). The taget (with the projectile in it) flies off after being struck. What percentage of the projectile's incident kinetic energy does the target (with the projectile in it) carry off...
