Math Problem Statement
A ball moves along a 1D coordinate system with the following motion parameters at time t = 0 s: x0 = 6.7 m and v0 = 0 m/s. The ball has a constant acceleration of 2.6 m/s2 during the entire motion which occurs over a time of 3.8 s. Assume that an error in position of 2 % is acceptable in this application over the entire motion. How many rows N will be needed in the table to model the entire motion to within the required error even though you are leaving out the final term of 1/2 a (Δt)2 ) present in the exact position expression?
