(a) Assuming P is large enough to make the block move, find the acceleration of the block as a function of P. (Use P as necessary and round numbers to the third decimal place.)

a(P) = m/s2

(b) If P = 6.81 N, find the acceleration and the friction force exerted on the block.

a =

Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. m/s2

Ffriction = N

(c) If P = 13.62 N, find the acceleration and the friction force exerted on the block.

a = m/s2

Friction = N

(d) Describe in words how the acceleration depends on P.

**bobpursley**, Wednesday, October 19, 2011 at 10:06pmforce P is adding to the normal force. Figure that first.

normalforce=mg+Psin39

friction force= mu(mg+Psin39)

Pcos39-mu(mg+Psin39)=ma solve for a
