The 332-Mg jet airliner has three engines, each of which produces a nearly constant thrust of 213 kN during the takeoff roll. Determine the length s of runway required if the takeoff speed is 226 km/h. Compute s first for an uphill takeoff direction from A to B and second for a downhill takeoff from B to A on the slightly inclined runway. Neglect air and rolling resistance. Assume 0 = 0.6°. B Horizontal Answers: Uphill from A to B: m Downhill from B to A: S= i

Body U with mass 5m is stacked on the top body W with mass m, and released. The bodies are in contact along the frictionless interface at 45° to the vertical. The body U is in contact with the frictionless vertical wall. Body W lies on the floor with coefficient of friction u. Relevant dimensions are shown in the figure. Express the results in terms of given quantities: m, g, h and µ (except when µ is given numerically). You need not evaluate sin 45° = cos 45° = 2/2. h U: 5m C 45 D W: m 3h

: A pilot in a fast jet aircraft loops the loop. The radius of the loop is 400 m, and the aircraft has a speed of 150 m/s when it passes through the bottom of the loop. What is the apparent weight that the pilot feels; in other words, what is the force with which she presses against her chair? Express the answer as a multiple of her normal weight

A lady on a bicycle is going down a hill. If the initial slope angle θ1 = 5 and she has a constant speed with no braking or pedaling, determine the drag force asserted on bicycle tires by the ground (Assume the total mass for her and the bicycle is 70 kg and neglect air resistance).
