In the given system; the work done by gravity on mass of 5 kg just before m2 hitting the ground will be ( ). (Take g=10m/s2)
The work done by gravity W = mgh,
where m is the mass, g is the acceleration due to gravity , and h is the height.
The mass m2 = 10kg is falling a distance h = 2m.
Since the pulley system is connected, the distance moved by m1 is also 2m.
Next, calculate the work done by gravity:
substitute m = 5kg, Click "Show Answer" to reveal the answer and analysis
