you're right, my mistake. :redface: Thanks for your help!

because the diameter of the wheel is 10? so half of it would be the radius of 5?

would i use C=2pir? c= 2(3.14)(5) = 31.4 cm?

Homework Statement image host A solid sphere rolls without slipping down an incline and compresses a spring. The figure above shows the system with the spring compressed to its turning point (at maximum compression, where the sphere’s velocity is zero.) Assume that no energy is lost due...

Thanks for your reply! So for b) would the angular speed would be .4s? c) would it be 0? since it goes from -8 to 8 ?

Homework Statement The black curve represents the position of a spot on the x-axis projection of a spinning wheel. a) Which curve represents the velocity of that spot? blue b) What is the angular speed of the wheel? c) What is the tangential speed of the wheel, assuming the full...
