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 a = 3 − 0.3t if 0 ≤ t ≤ 10 0 if t > 10. if the raindrop is initially 500 m above the ground, how long does it take to fall? (round your answer to two decimal places.)
