Question

interpreting a motion map
which scenario could produce this motion map?
theo throws a tennis ball against a wall and it
bounces off.
pilar is walking to her car, stops to check for her
keys, and turns around to get them from her house.
anja throws a dart at a dart board and hits the
bulls - eye.
gabriel is running, stops to check for oncoming
traffic, and continues running in the same direction.

Explanation:

• Theo's scenario: When a tennis ball is thrown against a wall and bounces off, the motion changes direction. But the motion map shows a continuous change in velocity (indicated by the length of the arrows) in one - direction (initially) and then in the opposite direction. However, in this case, the ball's motion is more of an instantaneous change (bounce) rather than a gradual change as shown in the motion map.
• Pilar's scenario: Pilar is walking (motion in one direction), stops (no motion - represented by no arrow for a moment), and then turns around (motion in the opposite direction). The motion map shows a change in direction (arrows changing from right - to - left), which is consistent with Pilar's action of turning around.
• Anja's scenario: Throwing a dart at a dartboard and hitting the bull's - eye is a one - direction motion (towards the dartboard) until it stops. There is no change in direction as shown in the motion map.
• Gabriel's scenario: Gabriel stops and then continues in the same direction. The motion map shows a change in direction (arrows change from right - to - left), so this is not consistent.

Answer:

Pilar is walking to her car, stops to check for her keys, and turns around to get them from her house.
