If the velocity of an object changes from 15 m/s to 50 m/s during a time interval of 4 s, what is the acceleration of the object? if the acceleration in problem 4 is constant, what's the average velocity of the object in the previous problem?

The object's average acceleration over the 4s interval would be

Under constant acceleration, the average veclocity of an object with initial velocity and final velocity is

so assuming "problem 4" refers to the first question, the average veclocity of the object would be

i think it would be 43 movies that would have to be watched.

step-by-step explanation:

think about it. for the second plan, every month is 8 dollars. 8 x 12= 96. so thats the number for the second plan. now for the first plan, its annual meaning you have to pay 10 dollars every year. so now you have to get an equivalent amount of 86 since 96-10=86. 86 divided by 2 since every movie costs 2$ then you would have to watch 43 movies a year to get the same as the second plan. i really hoped this . have a wonderful day as well!

answer: its c because when it has a magnet next to it it will move away from the mixture. hope this
