The total charge a battery can supply is rated in ma⋅h, the product of the current (in ma) and the time (in h) that the battery can provide this current. a battery rated at 1000 ma⋅hr can supply a current of 1000 ma for 1.0 h, 500 macurrent for 2.0 h, and so on. a typical aa rechargeable battery has a voltage of 1.2 v and a rating of 1800 ma⋅h. for how long could this battery drive current through a long, thin wire of resistance 28 ω ?

The 20@kg wheel has a radius of gyration about its center g of kg = 300 mm. when it is subjected to a couple moment of m = 50 n # m, it rolls without slipping. determine the angular velocity of the wheel after its mass center g has traveled through a distance of sg = 20 m, starting from rest.

An alien spaceship is 500 m above the ground and moving at a constant velocity of 150 m/s upwards. how high above the ground is the ship after 5 seconds?

Aplayground slide is 8.80 ft long and makes an angle of 25.0° with the horizontal. a 63.0-kg child, initially at the top, slides all the way down to the bottom of the slide. (a) choosing the bottom of the slide as the reference configuration, what is the system's potential energy when the child is at the top and at the bottom of the slide? what is the change in potential energy as the child slides from the top to the bottom of the slide? (include the sign of the value in your answer.)
