The thrust generated by a single jet engine a for s F=59000n. It take the plane (with a mass of m=6300kg) a distance of D =0.95km to take off How far meters would you need to depress spring k=100,000 N/m in order to launch the plane at the same speed without help from the engine?

After being released from the top of a frictionless 30˚ ramp, abox of mass 20 kg slides 5.0 meters along the ramp until it hits a (massless) spring of constant k= 80N/m. Find the maximum compression of the spring.

: 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

graduate who joined the Navy as a pilot is about to take off in an F-15 (WF15 = 81,000 lb) from an aircraft carrier traveling at VA = 40 mph. The jet is launched from the catapult system (a connection just below the deck that assists the aircraft) with the force (Fcp) vs time curve shown that has points of F₁ = 1,000 lb at t₁ = 2 s and F₂ = 3,000 lb at t₂ = 5 s (the plane will reach the edge of the deck at t₂). The F-15 needs to be traveling at 170 mph to take off. Determine how much constant thrust (FTR) the engines must produce during the launch to reach this speed. F2 F₁ FCP t₁ VA t₂ FTR t (s)

v(3) A crate of mass m = 10 kg is "lifted" from rest by a rope with a force given by F = 75√t N. Find the speed of the box at t = 3 s and at t = 6 s. How much higher is the box, measured from its starting position, at t = 6 s? Use impulse and momentum, I guess = v(6) = y(6) m S m 8 m m F CC UBC Engineering

A 2500 Ib car traveling 60 mph (88 ft/s) impacts a highway crash barrier as shown below. If the barrier were designed to exert the following force over the 40 ft distance of the barrier, how far would you expect the car to travel after impacting the barrier? 20 ft 40 ft 20,000 lbs Force (Ibs) 10,000 lbs Distance (ft)
