Question
The s -t graph for a train has been experimentally determined. For 0 <t< 30 s, the curve is s = (0.4t2) m, and then it becomes straight for t > 30 s. (Eigure 1) Choose the correct a -t graph for the motion; 0 <t< 40 s. a (m/s²) 0.8 -t (s) 30 40 Figure 1 of 1 <> a (m/s*) s (m) 0.4 600 360 t (s) 30 40 a (m/s³) t(s) 30 40
