Question

For a fighter jet launched from an aircraft carrier, what is the work done by the catapult if the kinetic energy at lift-off is 6.2410^7 J and the thrust of its engines is 4.0410^5 N?

a) 1.2910^5 J
b) 2.3510^7 J
c) 3.2110^7 J
d) 4.1210^8 J

Answer 1

The work done by the catapult cannot be determined without knowing the angle theta.

Step-by-step explanation:

To calculate the work done by the catapult, we can use the equation:

Work = Force * Distance * cos(theta)

In this case, the force is the thrust of the engines, which is 4.04 x 10^5 N, and the distance is the length of the runway, which is 90 m. The angle theta is not provided in the given information. Without knowing the angle, we cannot determine the work done by the catapult. Therefore, it is not possible to determine the correct answer from the given options.
