MCV4U Name: SWYK: Velocity & Acceleration 1. The position of an object (in meters) relative to the origin at time t (in seconds) is given by s(t )=t' -15t + 63t -81. Find a) the velocity when the object is at the origin b) the average velocity between 3 and 6 seconds c) when the object is moving toward the origin d) the total distance travelled in the first 12 seconds
