Please help me answer the following Physics question:

1. Suppose you measure the velocity of a runner as a function of time to be v, = bit - bat, where by, by are constants. v, is measured in meters/second, and t is measured in seconds. (a) (10 points) What are the units of by? What are the units of by? (b) (10 points) What is the runner's acceleration a, at time t? (c) (10 points) Assuming you know bj and be, do you have enough information to know the runner's position x at time ? Why or why not
