EF MONG gn unOW3 LIlat uie TIIle will IIUve II uie urecLIon OPpositc Big Idea The law of conservation of momentum shows that nothing in the universe is unaccounted for. This is what makes this law indispensable in investigating vehicular accidents (e.g., to identify the culprit). What Have I Learned So Far? Solve. Show your complete solutions. 1. Yeonjun works as an astronaut who has been sent to the International space Station (ISS) At one instance while he is at rest, Yeonjun throws a 5.0-kg bowling ball away from him at a rate of 2.0 m/s relative to the ISS. At what speed and direction will he start to move after he releases the ball? TE a In a 2. Suppose you find yourself in the middle of a frictionless icy floor.

15 kilometers Questions: a. How long does it take Mario to reach school considering his average speed? b. If x represents the time it takes Mario to drive to school with the given distance of 15 kilometers, how will you represent the relationship of his speed (y) versus the time (x)? c. Mario's average speed as 30 kilometers per hour. Suppose Mario lowers his speed by 10 kilometers per hour, how long will he reach the school given the same distance? d. Suppose Mario's speed is unknown and represented by (x), he lowers his speed by 10 kilometers per hour at a distance of 15 kilometers and reaches school at 3 hours, 4 - how will you write the equation to find his average speed (x)? e. Mario's average speed was 30 kilometers per hour. He plans to drive for another 30 kilometers from school, how long will it take him to cover the whole distance (house to school to 30 kilometers from school)? f. If Mario drives another (x) kilometers from his school at an average speed of 30 kilometers per…
