Question

Use the VELOCITY vs. TIME graph below to answer the following questions. Let south be the positive direction & north be the negative direction. Express all answers in the appropriate mks units. NOTE:m/s2 should be entered as m/s 2. VELOCITY vs. TIME GRAPH A.) Over what period of time was the object speeding up? B.) Over what period of time was the object slowing down? C. Over what period of time was the objects velocity constant? D.) State the magnitude &direction of the objects acceleration at 5 s E. State the magnitude & direction of the objects acceleration at 80 s. F. State the magnitude & direction of the objects acceleration at 210 s x-velocity (m/s) to 50s 20 150sto 250s 150 s 10 to 150 s Choose direction-▼ -Choose directionT -10 | Choose direction … ▼ -20 t (s) 50 100 150 200 250Please Explain D, E and F. in details, because I didn't understand them.
