Un camión viaja a 90 km/h y a 15 metros se le atraviesa un perrito. El conductor frena a -6m/s2 a) ¿Cuánto tiempo tarda en detenerse?
b) Una vez empieza a frenar ¿Qué distancia necesita para detenerse? (tenga en cuenta que si se detiene la velocidad
final es 0)
c) ¿Estrella al perrito?

Matt is driving down 7th street. he drives 150 meters in 18 sec. assuming he doesn’t slow down or speed up, what is his speed?

In positive numbers less than 1, the zeros between the decimal point and non zero are significant

Suppose water is leaking from a tank through a circular hole of area ah at its bottom. when water leaks through a hole, friction and contraction of the stream near the hole reduce the volume of water leaving the tank per second to cah 2gh , where c (0 < c < 1) is an empirical constant. a tank in the form of a right-circular cone standing on end, vertex down, is leaking water through a circular hole in its bottom. (assume the removed apex of the cone is of negligible height and volume.) (a) suppose the tank is 20 feet high and has radius 8 feet and the circular hole has radius 2 inches. the differential equation governing the height h in feet of water leaking from a tank after t seconds is dh dt = − 5 6h3/2 . if the height of the water is initially 8 feet, how long will it take the tank to empty? (round your answer to two decimal places.)
