Anail is partially inserted into a block of wood, with a length of 0.0300 m protruding above the top of the block. to hammer the nail in the rest of the way, you drop a 20.0 kg metal cylinder onto it. the cylinder rides on vertical tracks that exert an upward friction force of 16.0 n on the cylinder as it falls. you release the cylinder from rest at a height of 1.50 m above the top of the nail. the cylinder comes to rest on top of the block of wood, with the nail fully inside the block. use the work-energy theorem to find the speed of the cylinder just as it hits the nail.

with 5 seconds, no, but over time if the police car stays at 65m/s ad the speeding car stays at 60, then obviously yes, but the answer to your question would be, no.

hope this : )

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.
