1. The problem statement, all variables and given/known data An object is out in free space, in motion along a straight line, with a constant acceleration of 15 m/s2. At time t = 0, the object is at x = 0 meters, with a velocity of -80 m/s. Where is the object at t = 10s ? a. - 50 m b. 20 m c. - 4 m d. 75 m 2. Relevant equations 3. The attempt at a solution I'm not even sure how to start this problem. This class for some reason does not use calculus, and the teacher is terrible so I have no idea what to do. My best guess would be that 70m and the way I tried this was assuming since V= -80 m/s and constant accel - 15m/s2 that t1= -65m and then to add 15 m every second until t10 = 70. Only problem is this is not an answer. What should I do?
