A block having a weight of G is placed on the rough surface of the triangular prism ABC. The coefficient of static friction between the block and the surface is f, and f> tan. The triangular prism is moving to the left with a constant acceleration a. Determine the biggest acceleration to keep the block relatively resting on the surface.

Plz use g = 9.8 m/s2

Ⓒ Macmillan Learning An engineer wants to design an oval racetrack such that 3.20 × 10³ lb racecars can round the exactly 1000 ft radius turns at 96 mi/h without the aid of friction. She estimates that the cars will round the turns at a maximum of 175 mi/h. Find the banking angle necessary for the race cars to navigate the turns at 96 mi/h without the aid of friction. 0 = This banking and radius are very close to the actual turn data at Daytona International Speedway, where 3.20 × 10³ lb stock cars travel around the turns at about 175 mi/h. What additional radial force is necessary to prevent a race car from drifting on the curve at 175 mi/h? radial force: N
