Vectors in rectilinear motion

Which of the following is not an example of a Scalar?

• Velocity

• distance

• time

• speed

A Vector requires both a magnitude (size) and a ..................................

Find the resultant vector when the following vectors are combined.

8m west, 5m east and 4m west

• 1m East

• 9m West

• 7m East

• 7m West

When adding Vector B to Vector A using the head to tail method, from what point, and to what point is the resultant vector drawn?

• From the head of B to the tail of A

• From the head of A to the tail of B

• From the tail of B to the head of A

• From the tail of A to the head of B

Vector A is 5m West. Vector B is 4m East. When Vector A is subtracted from Vector B, the resultant is:

• 1m East

• 1m West

• 9m East

• 9m West

A student throws a ball up into the air at 3m/s. A short time later the ball falls downwards at a velocity of 4m/s. Determine the change in velocity for the ball during this time.

• 7m/s downwards

• 7m/s upwards

• 1m/s upwards

• 1m/s downwards
