Question

You have been given the job of designing a truck-mounted launcher for an unpiloted drone aircraft. This drone, designed to monitor atmospheric pollution levels, needs a minimum speed of 3.4 m/s to fly. It will be launched by a compressed-air catapault, which applies a constant force F as the drone moves along a track of length 5.7 m. If the drone has a mass of 3.2 kg, how much force F must the compressed air catapault provide?

Type your answer, in Newtons, to at least one decimal place.

Explanation / Answer

conserving energy we have work done by force F = change in kinetic energy of the drone => F*5.7 = 1/2*3.2*(3.4^2) => F =3.2449 N
