A flight attendant pulls her 74 Nflight bag a distance of 318 m along alevel airport floor at a constant velocity. The force she exerts is36 N at an angle of 54° above the horizontal.
(a) Find the work she does on the flightbag.
J
(b) Find the work done by the force of friction on the flightbag.
(c) Find the coefficient of kinetic friciton between the flight bagand the floor.
Two forces act on a 6.5 kg object sitting on friction-less horizontal surface and force is 25N in the(+) x-direction and the other is 35N in the (-)x-direction. What is the accelertation of the object

A thin rod (length = 1.816 m) is oriented vertically, with its bottom end attached to the floor by means of a frictionless hinge. compute the magnitude of the angular acceleration of the rod
A playground merry-go-round of radiusR=2.00m has a moment of inertiaI=255kg·m2and is rotating at9.0rev/min about a frictionless vertical axle. What is the new angular speed of the merry-go-round
A 1100 kg car is moving at a speed of 40.0 m/s. How much work is required to bring the car to rest
A 2 kg mass is pushed 0.5 m into a spring with spring constant 200 N/m on a frictionless horizontal surface. Upon release, the mass travels across the surface until it encounters a rough incline. The mass moves up incline and stops at a height of ..
The femur is a bone in the leg whose minimum cross-sectional area is about 4.5 x 10-4 m2. A compression force in excess of 7.7 x 104 N will fracture this bone. Bone has a compression Young's modulus of 9.4 x 10^9 N/m2
