1.-) Se procede a realizar a lanzar ciertos objetos por medio de un equipo apoyado en el piso con un ángulo de inclinación de 45o , siendo disparados con una velocidad inicial de 180 km/h. Cuál sería la altura máxima alcanzaran los platos?

2.-) Se lanza unas pelotas con un disparador que tiene un ángulo de inclinación de 75o y con una velocidad de 25 m/s. Calcular:

a.) La altura máxima que alcanza las pelotas.

b.) El tiempo de vuelo que permanece en el aire.

c.) El alcance horizontal a que se caerían las pelotas al piso.

3.-) Un Objeto es lanzado y realiza un movimiento parabólico con una velocidad inicial de 85 m/s y un ángulo de 65o , Calcular el tiempo de vuelo del objeto lanzado.

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.

if they have a finite resultant

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
