Homework Help: physics

Posted by sarah on Monday, May 26, 2014 at 12:52am.

An aircraft has an initial mass of m0 and an initial acceleration of a0. After flying for 2 hours, the mass of the aircraft has decreased by 11%, due to the burning of the fuel. If the propulsive force provided by the engines is constant, what is the expression for the new acceleration, a2, at this time? You may assume that the aircraft is in level flight at all times and the air resistance is negligible.

Select one:
a. a2=0.89a0
b. a2=a0/0.89
c. a2=1.11a0
d. a2=1+0.11a0
