Astudent standing on the ground throws a ball straight up. the ball leaves the student's hand with a speed of 16.0 m/s when the hand is 2.20 m above the ground. you may want to review (pages 49 - 51) . for with math skills, you may want to review: quadratic equations for general problem-solving tips and strategies for this topic, you may want to view a video tutor solution of time in the air for a tossed ball.

tube or goog will be great resources to find the answer to the question that you're asking

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.

another example of kinetic energy would be,

kinetic energy   >     moving energy

answer: at 24 february, 2014 the population gets twice of its initial population.

explanation:

since we have given that

the population for alpha city, t years after january 1, 2004 is given as

first we find out the initial population, i.e. t=0,

so, our quadratic equation becomes,

according to question, we have said that if the population has twice its initial population, then it becomes

so, time taken to reach this above mentioned population is given by

now, we know that time can't be negative so, we take t=9.149 years.

hence, at 24 february, 2014 the population gets twice of its initial population.
