Ablock of mass m is pressed against an ideal spring of constant k, compressing the spring by an amount d. the block is released, and slides on a frictionless surface. when it reaches the equilibrium length of the spring, it leaves the spring and continues to slide until it collides elastically with a statonary block of mass m2 = m/3. find each of the following. your answers should be expressed in terms of k, m, and d. a) the velocity of the large block when it leaves the spring b) the velocity of the large block after the collision c) the velocity of the small block after the collision

answer: good job it's all correct !

explanation:

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.
