A particle moves in a straight line so that its velocity at time
riadik2000 [5.3K]

Answer:

s(2) = 7.75

Step-by-step explanation:

given the velocity v(t) = t^3

we can find the position s(t) by simply integrating v(t) and using the boundary conditions s(1)=2

s(t) = \int {v(t)} \, dt\\ s(t) = \int {t^3} \, dt\\s(t) = \dfrac{t^4}{4}+c

we know throught s(1) = 2, that at t=1, s =2. we can use this to find the value of the constant c.  

s(1) = \dfrac{1^4}{4}+c\\4 = \dfrac{1^4}{4}+c\\c = 4-\dfrac{1}{4}\\c = \dfrac{15}{4} = 3.75

Now we can use this value of t to formulate the position function s(t):

s(t) = \dfrac{t^4}{4}+\dfrac{15}{4}\\

this is the position at time t.

to find the position at t=2

s(2) = \dfrac{2^4}{4}+\dfrac{15}{4}\\

s(2) = \dfrac{2^4}{4}+\dfrac{15}{4}\\

s(2) = \dfrac{31}{4} = 7.75

the position of the particle at time, t =2 is s(2) = 7.75

How many elements are in the set​ {x | x is an even prime​ number, x<150}​?
Bond [772]

Answer:

The set {x | x is an even prime number, x<150} has 1 element.

Step-by-step explanation:

Prime Numbers: The numbers which have no factors other than 1 and the number itself are called prime numbers.  

Even Numbers are those numbers which are completely divisible by 2.

So, the only EVEN PRIME NUMBER = 2

Now, Set = {x | x is an even prime number, x<150}

So, the set has {2} as its only element.

Hence, the total elements in the set is 1.

Or, the set {x | x is an even prime number, x<150} has 1 element.
