Compute the overall heat-transfer coefficient for a frame construction wall made of brick veneer (120 lbmft) with 3 in. insulation bats between the 2 × 4 studs on 16 in. centers; the wind velocity is 15 mph.

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.
