Question

7. Consider the \( 65.0 \)-kg ice skater being pushed by two others shown in Figure 5.19. (a) Find the direction and magnitude of \( \mathbf{F}_{\text {tot }} \), the total force exerted on her by the others, given that the magnitudes \( F_{1} \) and \( F_{2} \) are \( 26.4 \mathrm{~N} \) and \( 18.6 \mathrm{~N} \), respectively. (b) What is her initial acceleration if she is initially stationary and wearing steel-bladed skates that point in the direction of \( \mathbf{F}_{\text {tot }} ? \) (c) What is her acceleration assuming she is already moving in the direction of \( \mathbf{F}_{\text {tot }} ? \) (Remember that friction always acts in the direction opposite that of motion or attempted motion between surfaces in contact.)

(a) Find the direction and magnitude of 𝐅tot, the total force exerted on her by the others, given that the magnitudes F1 and F2 are 26.4 N and 18.6 N, respectively. (b) What is her initial acceleration if she is initially stationary and wearing steel-bladed skates that point in the direction of 𝐅tot ? (c) What is her acceleration assuming she is already moving in the direction of 𝐅tot ? (Remember that friction always acts in the direction opposite that of motion or attempted motion between surfaces in contact.)
