A diver performing a double somersault spins at an angular speed of 4.5 π rad/s precisely 0.70s after leaving the platform. Assuming the diver begins with zero initial angular speed and accelerates at a constant rate, what is the divers angular acceleration during t...
A girl sitting on a merry-go-round moves counterclockwise through an arc length of 3.36m. If the girls angular displacement is 2.96 rad, how far is she from the center of the merry-go-round? Answer in units of m.
A ﬁgure skater begins spinning counterclockwise at an angular speed of 4.6π rad/s. During a 4.6s interval, she slowly pulls her arms inward and ﬁnally spins at 7.6π rad/s. What is her average angular acceleration during this time interval? Answer in uni...
The tension in a string from which a 5.4kg object is suspended in an elevator is equal to 53.02N. What is magnitude of the acceleration a of the elevator? The acceleration of gravity is 9.8 m/s^2
A 40.7kg wagon is towed up a hill inclined at 18.1 degrees with respect to the horizontal. The tow rope is parallel to the incline and has a tension of 139N in it. Assume that the wagon starts from rest at the bottom of the hill, and neglect friction. The acceleration of gravi...
Karen has a mass of 62.60 kg and she rides the up escalator at Woodley Park Station of the Washington D.C. Metro. Karen rode a distance of 62 m, the longest escalator in the free world. How much work did the escalator do on Karen if it has an inclination of 35°?
An 845-N sled is pulled a distance of 190 m. The task requires 1.70 104 J of work and is done by pulling on a rope with a force of 124 N. At what angle is the rope held?
I(220-a-r)+r I=.5 a=45 r=85
Can you please give me a example of a - and + multi step equation
There is a 10/49 chance that BOTH of them are running.
