Easily. Lois’s position is 4.9t^2 for t >= 0. Superman’s is 12×4.9(t – 0.75)^2 for t >= 0.75. Solving for t gives
4.9t^2 = 12×4.9 (t – 0.75)^2
t^2 = 12(t – 0.75)^2
t = sqrt(12) (t – 0.75)
(taking the solution where t > 0.75)
0.75 sqrt(12) = t sqrt(12) – t
t = 0.75 sqrt(12)/[sqrt(12) – 1] = 1.054 seconds.
Their position then is 4.9 × 1.054^2 = 5.44 meters below the top of the building, plenty of time for Superman to decelerate before they reach the ground.
Old riddle, time gap from northbound to southbound is one-fifth that of southbound to northbound (if Alice is north), so southbound buses arrive five minutes after northbound buses.Bob should flip a coin and take the second bus half the time.
Since there are about 12.37 lunar months in a year, some years have 13 full moons. The named moons were the first, second, and last of each season, starting a year with the vernal equinox. The original definition of a blue moon was the third full moon in a season that had four full moons.
Can’t remember the last time we saw Crumbs when he wasn’t being thrown off a crashing bicycle. Was it when Kevin demonstrated to Miles what happens when Kevin yanked Crumbs out of Kody’s hands?
I think Riley is forced to absorb much of Huey’s vocabulary by having to listen to him.Such a shame his teacher here, Ms. Peterson, wasn’t in the cartoon.
