Answer: $25.08\ m/s^2$

Explanation:

Given

mass of wagon m=5 kg

elevation

$\theta =30.9^{\circ}\\F=150\ N$

Sin component of weight will oppose the applied force therefore we can write

$F-W\sin \theta=ma\\where\\W=weight(mg)\\a=acceleration$

$150-5\times 9.8\times \sin (30.09)^{\circ}=5\times a\\125.43=5a\\a=25.08\ m/s^2$
