The figure shows an object's acceleration-versus-force graph. (Figure 1) Figure1 of 1The plot shows the acceleration in meters per second squared as a function of force in newtons. The acceleration is increasing linearly from 0 newtons and 0 meters per second squared to 1 newton and 4 meters per second squared.

Part A
What is the object's mass?

The answer is    (d) 7/2======we have    we also  have an integral      notice how function f splits up at x = 0. there's a left piece and a right pieceso we'll need to do the same thing with our integral: split it at x = 0we use a property of integrals that allows us to split up and sum:     notice that for the piecewise function f, the function has the equationf(x) = x when x  ≤ 0. so for the integral  , f(x) = x so it changes into      for the piecewise function f, the function has the equationf(x) = x+1  when x  > 0. for the integral  , we have    therefore, back to our splitted integral:
