Question 2. The relation between acceleration and time for the table slide

Question 2. The relation between acceleration and time for the table slide of a milling machine-tool starting from rest is given by the data time in seconds 0 10 20 30 40 50 60 70 (1) acceleration in ft/sec 0.5 1.0 1.2 0.5 -0.3 -0.45 -0.45 -0.3 (i) Sketch the acceleration-time graph with the acceleration a on the vertical axis and time t on the horizontal axis. (ii) Obtain expressions for the change in velocity and displacement as functions of time when acceleration is constant (iii) Use the data in the table to determine the velocity-time and displacement-time graphs
