1.	In the following speed time graph: (a) When is the object in uniform motion? (b) During which time interval is the acceleration maximum? Justify doing calculation for acceleration for each time interval.(c) When is the object at rest?(d) During which time interval is the acceleration negative?(e) Calculate the negative acceleration too.
Answer» CT is uniform in 15 from yaxis and 10 from x axis to20 in x axisb)from time interval 0-10 and speed 0-15 ACCELERATION will be morea=15-0\10-0=1.5c)at 0 OBJECT is at restd)from time interval 30-50 acceleration will be negativee)a=25-50\50-30=-25\20=-1.25
