A62.0-kg skier is moving at 6.60 m/s on a frictionless, horizontal, snow-covered plateau when she encounters a rough patch 4.60 m long. the coefficient of kinetic friction between this patch and her skis is 0.300. after crossing the rough patch and returning to friction-free snow, she skis down an icy, frictionless hill 2.50 m high.

Heena wants to measure the volume of a ball that is 24 cm across. how should she set up her equation?

If angle "a" is 25°, angle "b" is: a) equal to angle c b) less than angle c c) greater than angle c
