An object is launched vertically in the air at 41.6541.65 meters per second from a 99-meter-tall platform. using the projectile motion model h (t )equals negative 4.9 t squared plus v 0 t plus h 0 commah(t)=−4.9t2+v0t+h0, where h(t) is the height of the projectile t seconds after its departure, v 0v0 is the initial velocity in meters per second, and h 0h0 is the initial height in meters, determine how long it will take for the object to reach its maximum height. what is the maximum height?

On a hot saturday morning while people are working inside, the air conditioner keeps the temperature inside the building at 22degreesc. at noon the air conditioner is turned off, and the people go home. the temperature outside is a constant 33degreesc for the rest of the afternoon. if the time constant for the building is 4 hr, what will be the temperature inside the building at 4 : 00 font size decreased by 2 upper p . font size decreased by 2 upper m .? at 6 : 00 font size decreased by 2 upper p . font size decreased by 2 upper m .? when will the temperature inside the building reach 24degreesc? 324281
