⏩ a) F = ( m1 + m2 + m3 ) a

= ( 1 + 1.5 + 2 ) × 4

= 4.5 × 4 = 18 N.
__________________________

b) for m1 F - R1 = m1a = 1 × 4

=> F - R1 = 4

for m2 R1 - R2 = m2 a = 1.5 × 4 = 6

=> R1 - R2 = 6 N.

for m3, R2 = 6 N

=> R2 = 8 N.

c) contact force between m2 and m3 = R2 = 8N

Contact force between m1 and m2 R1 = R2 + 6 = 8 + 6 = 14 N.
