A hоrizоntаl fоrce F → (pаrаllel to the ground) is applied on a block of mass 5 . 00 k g that is on an incline of angle α = 35 . 00 ° , as shown in Fig. 1.1. The coefficient of static friction and the coefficient of kinetic friction between the block and the incline are 0 . 400 and 0 . 300 , respectively. (a) If the magnitude of F → is 40 . 00 N and the block is at rest, what are the magnitude and direction of the frictional force on the block? (b) If the magnitude of the force F → is increased, what is its magnitude if the block is at the verge of moving up the incline? (c) If the magnitude of F → is 90 . 00 N , what is the acceleration of the block? (d) If the magnitude of the force F → is decreased, what is its magnitude if the block is at the verge of moving down the incline? (e) What is the magnitude of F → if the acceleration of the block is 2 . 00 m s 2 down the incline? t2_phys2425.v01_q11.jpg
