Q. A 25 kg child on a 2.0 m long swing is released from rest when the swing supports make an angle of 30.0 degrees with the vertica.
a. What is the maximum potential evergy associated with the child?
b. neglecting friction, find the child's speed at the lowest position.
c. What is the childs total mechanical energy?
d. If the speed of the child at the lowest position is 2.00 m/s, what is the change in mechanical energy due to friction?
What is the instantaneous power, at a time of 0.00700 seconds, dissipated by a 200 ohm resistor in a resonant AC circuit powered by a generator with a 21.0 V greatest potential difference operating at 5000 rad/s .
The bowling ball has a diameter of 20.6 {rm cm}, and the angle the stick makes with the horizontal is 30.0 {rm ^circ}. You may suppose there is no friction between the stick and the bowling ball, though friction with the floor must be taken into acco..
