Which of the following quantities is a vector?

time

mass

temperature

acceleration

Answer explanation

Time, mass, and temperature do NOT have direction. Acceleration has direction, so it is a vector.

A plane is flying 100 mi/hr North and it encounters a wind blowing 30 mi/hr South. What is the resultant velocity of the plane?

70 mi/hr South

70 mi/hr North

130 mi/hr South

130 mi/hr North

Answer explanation

Draw this out.

100 mi/hr North minus 30 mi/hr South =

A vector is drawn so that 100 mi/hr is 5 cm long. How long would you draw a 50 mi/hr vector with the same scale?

2.5 cm

5 cm

7.5 cm

10 cm

Answer explanation

the scale would be

1 cm = 20 mi/hr

so a 50 mi/hr vector would be 2.5 cm long

(50 is half of 100, so the length would be half as well)
