Question

2) Four forces act on a 3.000 kg wooden block, released from rest, on a wooden table: FA=20.0 Nat 222.0, friction, the block's weight, and the normal force from the table. a) Calculate the normal force on the block, assuming the block remains on the table. b) Calculate the magnitude of the maximum static frictional force the table can exert on such a block under any circumstance. 3) For the previous problem, determine whether the block accelerates. If it does not, calculate the actual frictional force resisting the motion. If it does, calculate both the acceleration and the frictional force.

please include a free body diagram starting with this

Answer 1

- Sol) Free body diagram of the block 3 kg Floso ng + Fsino Here &r 200 and and al is normal We can see that oa 42° force mgt F Sino 3 (9.8) Nt Zofinugo N NE (Na 42.783 ) We given f = clore So for know that static friction is an. USN Us : Coefficient of static friction. fs to be man els = 1 nence Its = 42.783 N (6) Fonce is so acting Floso and E coso e in horizontal direction frictional force. 20 Cos42 = 14.863 N.

which is less than static force. so block does not so actual friction force to applied force which If = 14.863N friction accelerates. is equal is
