hi,
i have 5 questions i need the
complete solutions with their final results. is there anyonecouldhelp
me, i would appreciate that.
1)
2600 rev/min is equivalent to which of the following?
1. 273 rad/s
2. 43.3 rad/s
3. 2600 rad/s
4. 60 rad/s
2)
A 0.30-m-radius automobile tire rotates how many rad afterstartingfrom rest and accelerating at a constant 2.0 rad/s2 over a5.0-sinterval?
3)
A Ferris wheel starts at rest and builds up to a final angularspeedof 0.70 rad/s while rotating through an angular displacementof 4.9rad. What is its average angular acceleration?
4)
A Ferris wheel, rotating initially at an angular speed of0.50rad/s, accelerates over a 7.0-s interval at a rate of 0.040rad/s2.What is its angular speed after this 7-s interval?
5)
A point on the rim of a 0.30-m-radius rotating wheel hasatangential speed of 4.0 m/s. What is the tangential speed ofapoint 0.20 m from the center of the same wheel?
thank you in advance
