You are organizing a soap box derby on the slopes of Mount Trashmore. To
get approval from Parks and
Recreation, you are required to
provide proof that the cars will not
exceed a speed of 10 m/s. You
establish a research team to
construct a track and race car to
determine the maximum vertical
height the cars can begin the race
without exceeding 10 m/s at the finish
line. You will then use the data from
the research to obtain permits from
Parks and Recreation to hold the
event.

10 is the . . .

2. they have negligible mass.

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
