A catapult with a spring constant of 1.0 × 10⁴ newtons per meter is required to launch an airplane from the deck of an aircraft carrier. The plane is released when it has been displaced 0.50 meter from its equilibrium position by the catapult. The energy acquired by the airplane from the catapult during takeoff is approximately

• 1.3 × 10³ J

• 2.0 × 10⁴ J

• 2.5 × 10³ J

• 1.0 × 10⁴ J
