Convert the following hexadecimal numbers to binary: a) 0x3ac b)
0x
4f32a9 c)
0xc337

a) 3AC => 001110101100

b) 4F32A9 => 010011110011001010101001

c) C337 => 1100001100110111  

Explanation:

Converting the given hexadecimal numbers to binary:

a) 0x 3AC =>

Binary representation of individual hex digits:

3 = 0011

A=1010

C=1100

so 3AC => 001110101100

b) 0x  4F32A9 =>

Binary representation of individual hex digits:

4 = 0100

F = 1111

3 = 0011

2 = 0010

A = 1010

9 = 1001

so 0x 4F32A9 => 010011110011001010101001

c) 0xC337 =>

Binary representation of individual hex digits:

C = 1100

3 = 0011

7 = 0111

so 0x C337 => 1100001100110111

only #2 represents an object at rest on a table.

in #1, there is no normal force due to the table; the object is accelerating downward.

in #3, the vertical forces are not balanced; the object is accelerating downward.

in #4, neither the vertical nor the horizontal forces are balanced. the object is accelerating upwards and to the right.
