A child slides down a slide with a 28 degrees incline and at the bottom her speed is preisely half what it would have been if the slide had been firctionless. Caluclate the coefficient of kinetic friction bewteen the slide and the child.

my problem says: a projectile is fired with an initial speed of 75.2 m/s at an agle of 34.5 degrees above the horizontal on a long flat firing range. i figured out everyting so that y initial = 0 y = 92.6m Vy initial = 42.6 m/s Vy = 0 g = 9.8 m/s^2 t = 8.69 s Vx = 62 m/s the...
