A trolley is being pulled up an smooth incline plane by a man sitting on (as shown in figure). He applies a force of 250 N. If the combined mass of the man and trolley is 100 kg, the acceleration of the trolley (in $m / s^{2}$ ) will be [ $sin 1 5^{\circ} = 0.25$ ]
250 N $sin 1 5^{\circ} = 0.25$ ]

The man-trolley system is pulled up the incline by three rope tensions: 3 T = 750 N Along the incline: 3 T − m g sin 1 5 ∘ = ma 750 − 100 × 10 × 0.25 = 100 a a = 5 m/s 2
