Consider the 65.0 kg ice skater being pushed by two others shown in the figure. Frot F, F, Free-body diagram F2 F, (a) Find the direction (in degrees) and magnitude (in N) of Frot, the total force exerted on her by the others, given that the magnitudes F, and F2 are 22.0 N and 15.0 N, respectively. ° (counterclockwise from the direction of F, is positive) direction magnitude N (b) What is her initial acceleration (in m/s2) if she is initially stationary and wearing steel-bladed skates that point in the direction of Frot? (c) What is her acceleration (in m/s2) assuming she is already moving in the direction of F,tot? Remember that friction is always in the opposite direction of motion or attempted motion between surfaces in contact. m/s? (in the direction of Frot)
