Best Answer: We need to assume that once the driver started applying the brakes, the deceleration was constant. In the original situation, since the driver took 0.50 s to apply the brakes, he traveled 0.5 * 30 m/s = 15 meters before the brakes had any effect.
When zucchini plants get enough sun and water, they will continue to produce fruit for several months. Harvest zucchini when it is between 4 and 8 inches long and about 1 1/2 to 3 inches in diameter. Zucchini generally takes 35 to 55 days from planting until harvest. Zucchini fruit grows rapidly -- up to 2 inches per day, so it is best to harvest them every other day during the growing season.
Look for a uniform green color encompassing the entire zucchini. Look for zucchini that are 6 to 8 inches in length. Select zucchini that is fairly firm and not too soft. It should feel slightly more flexible than a cucumber, but not by much. Avoid soft zucchinis because the softness is a sign they will be inedible very soon.
