Please help me answer the following question in the next 20 minutes:

1. Suppose you measure the velocity of a runner as a function of time to he um = tut\" bat, where b1, b2 are constants. um is measured in metersJu'st-znocniuiiI and t is measured in seconds. {a} (10 points} What are the units of in? \"mat are the units of 12? {b} (10 points} What is the runner's acceleration am at time t? {c} (lllIlI points) Assuming you know in and 52, do you have enough information to know the runner's position :1: at time t? Why or with}.r not
