for each scenario below, choose the graph that gives the best representation. (a) a person standing on the ground throws a ball onto a flat rooftop. the ball rolls around for several seconds. then the ball falls off the roof, into a puddle of mud.
Answer
Explanation:
Step1: Analyze ball - throwing phase
When the person throws the ball onto the rooftop, the height of the ball increases with time in a non - linear (parabolic) fashion initially as it is under the influence of gravity while moving upwards.
Step2: Analyze ball - rolling phase
Once the ball is on the flat rooftop, its height remains constant for several seconds as it rolls around.
Step3: Analyze ball - falling phase
When the ball falls off the roof, its height decreases with time in a non - linear (parabolic) fashion as it is in free - fall under gravity.
Answer:
The second graph (the one with an initial upward curve, a flat section, and then a downward curve) gives the best representation.
