Texts: Given s = t + 3t, where s is in feet and t is in seconds. Find each of the following:
a) v(t)
b) a(t)
c) The velocity and acceleration when t = 2 sec
a) v(t):
b) a(t):
c) The velocity and acceleration when t = 2 sec:
When t = 2 sec, the velocity is (Simplify your answer.)
When t = 2 sec, the acceleration is (Simplify your answer.)
