MTH143 Unit 4 Review

Vector A is at 128 degrees with a magnitude of 156 km/hr. Vector B has a magnitude of 146 km/hr and is headed directly South. What is the resultant vectors magnitude and direction (as a principle angle). Round off to the hundredths.

If vector B is going north with a magnitude of 18m, and vector C is going East with a magnitude of 22m, what is the resultant vector and direction (with compass barrings). Round off to the hundredths.

If vector A is going East at 27 km and vector B is going West at 32 km. What is the resultant vector and direction

If vector A is going South at 101 km per hour and vector B is going North at 72 km per hour. What is the resultant vector and direction

 

If a boat goes South for 55 km and then turns East for 63 km. What is the resultant vector and direction as a principle angle. Round off to the hundredths if needed.

 

 

If a boat goes North for 40 km and then turns west for 16 km. What is the resultant vector and direction as a compass direction. Round off to the hundredths if needed

Vector A is 19 cm and is 80 degrees south of west. What is the y component?

round off to the hundredths if needed

Vector A is 177 mm and is 68 degrees south of east. What is the x component?

round off to the hundredths if needed

vector A is 45cm Ѳ=200ᵒ and vector B is 38cm Ѳ=50ᵒ, what is the magnitude and direction of the resultant vector? (give your final direction using a principal angle)

ROund off to the hundredths if needed.

vector C is 111 m Ѳ=305ᵒ and vector D is 240 m 64ᵒ south of west, what is the magnitude and direction of the resultant vector? (give your final direction using compass directions)

ROund off to the hundredths if needed.
