A 52.0 kg skater moves at 2.5 m/s and glides to a
stop over a distance of 24.0 m. Find the skater's
initial kinetic energy. How much of her kinetic
energy is transformed into other forms of energy by
friction as she stops? How much work must she do
to speed up to 2.5 m/s again?

Letter a, because when there are unlike charges they will always attract to each other.

Iassume the answer is 75 feet. inwards to outwards rather than outwards to inwards. probably be 75.hachures are stokes drawn in direction of the steepest slope. a series of short parallel lines drawn on a map to indicate topographic relief. it is actually called hachures on contour lines. the small marks in the center of the feature are called hachures.observe the picture attached

The answer is 4f======since electrostatic force is given by    we let f be the electrostatic force when  r = 1 m    if we let  denote the electrostatic force when the distance is decreased so that r = 0.5m, then    we established earlier that f = kq₁q₂. therefore    the force will now be 4f.

The answer is: c. from underground
