Homework Statement
An object moving with a constant acceleration travels 13 m in 7.8 s. The acceleration is then changed and the object covers an additional 34 m in 1.7 s. What is the average acceleration of the object over the entire interval described?
Homework Equations
Xf1 = 1/2(vo +vf)t
a=(vo +vf)/t
The Attempt at a Solution
vf1 =2(13)/7.8
vo =2(34)(1.7) - 44.2
a = (115.6-44.2)9.5
