An automated laboratory sled on a low-friction horizontal track is propelled by a constant horizontal thrust. The sled accelerates from an initial speed of 0.20 m/s0.20 \text{ m/s}0.20 m/s to a final speed of 1.80 m/s1.80 \text{ m/s}1.80 m/s with a constant acceleration of 0.25 m/s20.25 \text{ m/s}^20.25 m/s2. During this acceleration, the work done on the sled by the horizontal thrust is 11.52 J11.52 \text{ J}11.52 J.

Assuming resistive forces are negligible, calculate the magnitude of the horizontal thrust.
