Let v(t)=t^2−3t be the velocity, in feet per second, of an object at time t, in seconds.

a) What is the initial velocity? ___ ft/sec

b) When does the object have a velocity of zero? If there is more than time, list all answers in a comma separated list. ___ seconds

Question

Let   v(t)=t^2−3t   be the velocity, in feet per second, of an object at time t, in seconds. 
  
a) What is the initial velocity? ___  ft/sec 
  
b) When does the object have a velocity of zero? If there is more than time, list all answers in a comma separated list.   ___   seconds

Previous answer was wrong, has been deleted.
For the initial velocity plug in 0 for the time. The initial velocity is 0. It has a velocity of 0 at time t=0 and t=3
