Question

during the time interval from t=0s to t=4s the coordinate of an objects as a function of time is given by the expression x(t)=bt-ct at the instant t=4 secs the object comes to rest v=0m/s at x=32 m. determine the values of b and c

Answer 1

Am waiting for d answers

Answer 2

wow -- a whole minute already? Impatient much?

x(t) = (b-c)t
when x=32, you have
(b-c)*4 = 32
b-c = 8

I suspect a typo. Maybe you can fix it and plug in your numbers.
