Question

Lindsey travels 100 km/hr to the north. Josef travels 100 km/hr to the east. Lindsey and Josef have the same...

A. velocity
B. direction
C. speed
D. motion

Answer 1

Explanation:

Note: Remember the difference between a scalar and a vector.

A Scalar Quantity has a magnitude (numerical value) only. (Such as Speed, Time, Distance)

A Vector Quantity has a magnitude and a direction. (Such as Velocity, Displacement, Acceleration)

In this case,

B is out as they are of different directions.

A is ruled out too as the direction is different, the resultant velocity will be different as well.

D is ruled out as motion can come in many forms ,such as collision and bouncing.

So therefore answer is C as they have the same magnitude at 100 km/hr.
