Explanation / Answer

Only one question can be posted as per chegg guidelines

1.

1 Kg =1000 g

Therefore mass

M=(3171/1000)+43.9 =47.07 Kg =47.1 Kg (approx)

1 Kg =106 mg

M=4.71*107mg

2.

1 mile/hour =0.44704 m/s

Speed

V=65*0.44704 =29 m/s

3.

Magnitude

A=sqrt[42+(-6.9)2]=8

4.

Direction

o=tan-1(-2.7/5.5) =360-tan-1(2.7/5.5)

o=334o
