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

x> 6

step-by-step explanation:

8x+8> 7x+14

8x-7x> 14-8

x> 6
