Question Number - 08 (आयुष कुमार सोनी)

            🔰 Question Number - 08 🔰

Consider the 65.0-kg ice skater being pushed by two others shown in Figure 5.19. (a) Find the direction and magnitude of Ftot$size\; 12\{F\; rSub\; \{\; size\; 8\{"tot"\}\; \}\; \}\; \{\}$, the total force exerted on her by the others, given that the magnitudes F1$size\; 12\{F\; rSub\; \{\; size\; 8\{1\}\; \}\; \}\; \{\}$ and F2$size\; 12\{F\; rSub\; \{\; size\; 8\{2\}\; \}\; \}\; \{\}$ 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$size\; 12\{F\; rSub\; \{\; size\; 8\{"tot"\}\; \}\; \}\; \{\}$? (c) What is her acceleration assuming she is already moving in the direction of Ftot$size\; 12\{F\; rSub\; \{\; size\; 8\{"tot"\}\; \}\; \}\; \{\}$? (Remember that friction always acts in the direction opposite that of motion or attempted motion between surfaces in contact.)
