The actual question is “ Lucia raced her car on a raceway. She started the race at a standstill on the starting line , and when she finished the race , she was traveling 110 miles per hour . She wants to calculate her average acceleration. What other information will Lucia need to do so ? o A . The amount of fuel Lucia’s car used in the race
o B . The distance that Lucia traveled during the race
o C . The amount of time it took Lucia to finish the race
o D . What be Lucy‘s car halfway through the race

In order for the bug to fly through the air a force has to push the bug forward. identify this force. how does the bug produce

Part f - example: finding two forces (part i) two dimensional dynamics often involves solving for two unknown quantities in two separate equations describing the total force. the block in (figure 1) has a mass m=10kg and is being pulled by a force f on a table with coefficient of static friction îľs=0.3. four forces act on it: the applied force f (directed î¸=30â above the horizontal). the force of gravity fg=mg (directly down, where g=9.8m/s2). the normal force n (directly up). the force of static friction fs (directly left, opposing any potential motion). if we want to find the size of the force necessary to just barely overcome static friction (in which case fs=îľsn), we use the condition that the sum of the forces in both directions must be 0. using some basic trigonometry, we can write this condition out for the forces in both the horizontal and vertical directions, respectively, as: fcosî¸â’îľsn=0 fsinî¸+nâ’mg=0 in order to find the magnitude of force f, we have to solve a system of two equations with both f and the normal force n unknown. use the methods we have learned to find an expression for f in terms of m, g, î¸, and îľs (no n).
