What is this mass in grams? 8) If a mile is 5280 ft long and a yard contains 3 ft, how many yards are there in a mile?9) Area is found by multiplying the length of a surface and the width. If a floor measures 2.25 m?, how many square centimeters does this represent? 10) The volume of a cube is found by (length x width x height). If a cube has a volume of 2.5 m, what is the volume in cubic centimeters? 12 8 w/ tore 11) A cube has a certain volume. If the length of each side is quadrupled, by what factor will the volume increase? has Initial velocity of 6 in/'s slows down at a constant rate of -2 my's over a riad of 4 so s. What is the velocity at the end of this time? 12) Morganne walks a distance of 400 m with an average speed of 2 m/s. What time is required to walk the distance? Shur is the speed In km/h?13) Starting from rest, a car accelerates at a rate of 3 m/s' for a time of 4 seconds. What is the velocity at the end of the time? 14) A runner traveling with an initial velocity of 3 m/s accelerates at a constant rate of 1.5 m/s for a time of 5 seconds. What distance does the runner cover during this process? 15) A runner moving with an initial velocity of 6 m/s slows down at a constant rate of -2 m/s' over a period of 4 seconds. What is the velocity at the end of this time? 16) A car travels with an average speed of 60 MPH. What is the speed in km/h?17) if at a constant rate of speed: 3 m/s , for 5 seconds, starting from rest, draw a graph of distance vs time. 18) A ball is dropped from a diving platform. What is the velocity of the ball 1.5 seconds after the release? 19) From the problem 18, how far does it fall in 1.5 seconds of its flight? second after it is released? And its 20) A ball is thrown downward with an initial velocity of 10 m/s. What is the velocity of the ball 2 seconds after it is released?21) If a ball is thrown downward from a cliff of 20 m high and it takes 1.2 seconds to reach the ground, what will be an initial velocity of the ball? 22) A ball is thrown straight upward with an initial velocity of 15 m/s. How much time is required to reach the high point? 23) From 22, how high above its starting point is the ball 2 second after it is released? And its direction
