If the mass dropped doubles and speed remains the same, how does the graph change? Fill in the data table, plot the points, and make a smooth best-fit line in RED.

When professional athletes land after a jump, they are trained to land by bending their knees. Amateur athletes at times will jump and get injured when they land because they land stiff-legged.
On the graph, place an A where your think the athletic landing would be and place a B where the stiff-legged landing would be. No values for the graph were given.

Jumpers in the situation above have a mass of 100 kg and land at 2 m/s. The time of impact of a bending knees landing is 0.2 seconds. What is the force of impact? DON'T FORGET YOUR UNITS!!

Using evidence from the graph and calculations above, write a claim-evidence-reasoning (CER) statement of why landing stiff-legged causes more injury than landing with your knees bent.

There are two ways to catch a water balloon: not giving in with the catch and having the water balloon break or having “soft hands” and giving in with the impact.
On the graph, place an A where your think the water balloon would break and a B where the water balloon would stay intact.

The water balloon in the situation above weighs 0.5 kg and has a speed of 4 m/s. The time of impact of a breaking water balloon is 0.05 seconds. What is the force of impact? DON'T FORGET YOUR UNITS!!
