Blocks

C

(

1.8\,\text{kg}

) and

D

(

2.2\,\text{kg}

) slide in contact on a horizontal surface. The coefficient of kinetic friction between each block and the surface is

0.20

. A

20\,\text{N}

horizontal force is applied to block

C

, pushing both blocks to the right while they move together. Take

g = 9.8\,\text{m/s}^2

. Determine the magnitude of the normal contact force exerted by block

D

on block
