Awheel released from rest is rotating with constant angular acceleration of 3.0 rad/s a) (4 points) after 6.5 s, what is its angular velocity? b) (4 points) through what angle has the wheel turned? (4 points) how many revolutions has it made? c) (4 points) what is the speed of a point 1.0 m from the axis of rotation? d) (4 points) what is the magnitude of the total acceleration of the same point?

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.

the force represented by vector a is normal force. if the hockey puck is moving to the right, when it is hit with a significant force by the hockey stick the puck will move off in a different direction. correct on edge.
