A cyclist is standing still at the top of the hill and begins to coast down the hill. The mass of the cyclist and bike is 64 kg. the cyclist gravitational potential energy is converted into kinetic energy with an efficiency of 48%. What is her speed when she reaches a point that is a vertical distance 12 m lower than the point at which she started

the diagram which shows forces as either balanced = same speed or unbalanced = accelerarting

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

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.

i think the answer is tomato juice? not entirely sure though
