oo T-Mobile LTE 8:42 PM 13% D+ 9 session.masteringphysics.com Think And Sove 10.27 MasteringPhysics Think And Solve 10.27 You're in an airplane that flies horizontally with speed 970 km/h (270 m/s) when an engine falls off. Neglecting air resistance, assume it takes 28 s for the engine to hit the ground. Part A Find the height of airplane. Express your answer to two significant figures and include the appropriate units. H31 Value Units Submit Give Up Part B Find the horizontal distance that the aircraft engine falls. Express your answer to two significant figures and include the appropriate units.

Explanation / Answer

along horizantal

vx = 270 m/s

along vertical

voy = 0

displacement = y = -h

time taken = t = 28 s

from equation of motion

y = voy*t + 0.5*g*t^2

-h = 0 - 0.5*9.8*28^2

h = 3841.6 m <<-------answer

part(B)

along horizantal

Xe = vox*t = 270*28 = 7560 m <<------answer

part(C)

horizantal distance for airplane = xp = = vox*t = 270*28 = 7560 m

distance travelled are same

both are in same line

vrtical distance between them = h = 3841.6 m
