Since raindrops grow as they fall, their surface area increases and therefore the resistance to their falling increases. A raindrop has an initial downward velocity of 10 m/s and its downward acceleration is [9 – 0.94 if 0 st< 10 a if t> 10 If the raindrop is initially 500 m above the ground, how long does it take to fall?
