Question

Block 1 (3 kg) is located on the surface of a table. A hand pushes horizontally to the right on block 1 with a normal force of 27 N. The coefficient of kinetic friction between the block and the surface equals 0.2.
On a sheet of paper, draw the free body diagram for block 1 using the two-subscript notation from class. After completing the free body diagram, enter below each force and its x & y-components. Remember that the x-component is the "i" component and the y-component is the "j" component.

FORCES on BLOCK 1
A) Weight force on block 1 by Earth
W1E =  i +  j N

B) Normal force on block 1 by Surface
N1S =  i +  j N

C) Normal force on block 1 by Hand
N1H =  i +  j N

D) Frictional force on block 1 by Surface
f1S =  i +  j N

Tries 0/2

E) What is the acceleration a of block 1?
a =  i +  j m/s²
