Abody moving with constant acceleration covers the distance between two points 60.0 m apart in 6.0 seconds. its velocity as it passes the second point is 15 m/s. (a) what is its velocity at the first point? (b) what is the acceleration?

a)

b)

Explanation:

From the exercise we got final position, final velocity and how much time does it takes the body to cover the distance

From the concept of moving objects we know the following equations:

and

Now, we have two equations with two unknowns

(1)

Now, we need to replace (1) in the other equation

Solving for a

b)

Now, we can solve (1)

a)

which statement about this sum is true? −245+2.7
