Homework Statement A manufacturer of CD-ROM drives claims that the player can spin the disc as frequently as 1200 revolutions per minute. a. If spinning at this rate, what is the speed of the outer row of data on the disc; this row is located 5.6 cm from the center of the disc? b. What is the...

Sorry! The 10 degrees came from a different question, I looked off the wrong question, I've fixed it now.

I'm not sure, it just asks for acceleration, I still need help with this question.

Homework Statement An environmentally-sensitive daredevil wants to use a large mass, a rope, and a pulley to accelerate toward ramp while his motorcycle is in neutral, as shown below. If friction is negligible, what will the acceleration of the motorcycle be and the tension of the rope...

Ohhhhhhh, thank youuuuuuuuuuuuu. I re-did my whole thing and now it works!

I've done some changes, but I am still getting it wrong...

Yeah, I knew that, I should have included that too. I need actual with with the question though.

Homework Statement A 2.5 kg mass is attached to a 3.5 kg mass by a light string that passes over a friction-less pulley. The masses are released. a) What is the magnitude of the acceleration of the masses? b) What is the tension in the string? Homework Equations (I think) Ft - mg = ma The...

Yes, yours makes sense. I think this means that I've done the question correctly... Thank you so much!

Homework Statement A mosquito flies toward you with a velocity of 2.2 km/h (E). If you are traveling toward the mosquito with a speed of 1.9 m/s, and a distance of 21.0 m separates you and the mosquito initially: A) What will your displacement be when you hit the mosquito? (7) B) How long...
