For this assignment, you submit answers by question parts. The number of submissions remaining for each question part only change the answer. your last submission is used for your score. An airline fight attendant rolls a suitcase through the airport lobby as shown in the figure. If the magnitude of the force she exerts on the suitcase is 25.0 N and she does + 1.03 times 10^3 J of work in moving the suitcase a distance of 56.0 m, at what angle theta, above the horizontal (as shown in the figure below), is the force oriented with respect to the floor?

Explanation / Answer

W = Fd

W = Fdcos()

Given that the work done W is 1030 J, the force applied F is 25.0 N, and the displacement d is 56.0 m ,

1030 = 25.0(56.0)cos()

= cos^-1(1030/(25.0*56.0))

= 42.63 degree above the horizontal
