In landing activity, which variable should be maximized to minimize the risk of injury? Group of answer choices Change in acceleration Change in time Change in velocity Mass

A 3 kg ball is thrown straight into the air at 8 m/s . How high does it travel? Use g = 9.8 m/s Calculate answer to one decimal

An object kicked from ground level at an initial velocity of 84 m/s and an angle 0= 15 degree with ground What is the maximum height of the object in meter

A student wants to learn about falling objects, so she drops a hammer, paper ball and marble from three different heights. She records the drop time and final speed for each trial as shown on the diagram and the mass (in grams) of each object is shown. Notes Answers have 5% tolerance to allow for estimation. Note that you have multiple attempts for each answer, so we recommend checking answers one at a time. We also recommend Desmos' graphing application to create graphs when necessary! Hammer Paper Ball Marble (mass: 3565g) (mass: 93g) (mass: 68g) 30m 60m 90m 30m 60m 90m 30m 60m 90m 2.475 3.50s 4.28s 5.83s 10.35 14.8s 2.47s 3.50s 4.285 24.2m/s 34.3m/s 42.0m/s 6.68m/s 6.68m/s 6.68m/s 24.2m/s 34.3m/s 42.0m/s 1. True or False: If two objects are dropped from the same height, the more massive object will always fall faster.
