Question

As a 1.7×10? kg jet plane lands on an aircraft carrier, its tail hook snags a cable to slow it down. The cable is attached to a spring with spring constant 6.1×10? N/m. The spring stretches 29 m to stop the plane. Part A What is the elastic potential energy of the spring when the plane comes to a stop? Express your answer to two significant figures and include the appropriate units. U = [Value] [Units] Submit Request Answer Part B What was the plane's landing speed? Express your answer to two significant figures and include the appropriate units.

Step 1

So, U = 1/2 * 6.1*10^4 N/m * (29 m)^2 = 2.57*10^7 Joules. Part B: The plane's landing speed can be found by equating the kinetic energy of the plane just before it hits the cable to the elastic potential energy stored in the spring when the plane comes to a Show more…
