The purpose of this laboratory activity is to provide an opportunity for students to apply the principles of training in a fun, creative, and nonthreatening environment. Instructions: Students – your mission is to design and draw (or construct) a model of a piece of fitness equipment. The equipment may improve flexibility, muscular strength, muscular endurance, or cardiovascular fitness. Then you will describe what the item is and how it uses the principles of overload, progression, and specificity to improve the selected component of fitness. Upon completion students will save their Microsoft Office document and upload.

Aspacecraft can attain a stable orbit 300 kilometers above earth if it reaches a velocity of 7.7 kilometers per second. the formula for a rocket's maximum velocity v in kilometers per second is vequalsminus0.0098tplusc ln upper r, where t is the firing time in seconds, c is the velocity of the exhaust in kilometers per second, and r is the ratio of the mass of the rocket filled with fuel to the mass of the rocket without fuel. find the velocity of a spacecraft whose booster rocket has a mass ratio of 20, an exhaust velocity of 2.1 km/s, and a firing time of 15 s. can the spacecraft achieve a stable orbit 300 km above earth?
