Atransport plane takes off from a level landing field with two gliders in tow, one behind the other. the mass of each glider is 700 kg, and the total resistance (air drag plus friction with the runway) on each may be assumed constant and equal to 1600 n. the tension in the towrope between the transport plane and the first glider is not to exceed 12000 n. a)if a speed of 40 { m/s} is required for takeoff, what minimum length of runway is needed? b)what is the tension in the towrope between the two gliders while they are accelerating for the takeoff?

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
