"Lifting it too fast could snap the rope," the captain warned. " – force causes acceleration. Too much acceleration breaks things." 4. The rescue They used a hand-crank connected to a block-and-tackle. Alva felt the force in her arms. "This is mechanical advantage ," she said, sweating. "The rope pulls many times, so my force is multiplied."
Slowly, the chest rose. When it broke the surface, Milo gasped. "It worked!" np fysik åk 9
Captain Granit shook his head. "Water fights back. That's and drag ." "Lifting it too fast could snap the rope,"

Alva’s eyes lit up. "Wait, this is real physics. Let me think."
Milo groaned. "That sounds like a physics problem. I'm out."
