Aconveyor belt is used to send burgers through a grill- ing machine. if the grilling machine is 1.2m long and the burgers require 2.8min to cook, how fast must the conveyor belt travel? if the burgers are spaced 25 cm apart, what is the rate of burger production (in burgers/min)?

1.what is where an object is located 2. what is how fast an objects speed is changing 3. what is how fast an object is moving

Aparticle's position is given by x = 3.00 - 9.00t + 3t2, in which x is in meters and t is in seconds. (a) what is its velocity at t = 1 s? (b) is it moving in the positive or negative direction of x just then? (c) what is its speed just then? (d) is the speed increasing or decreasing just then? (try answering the next two questions without further calculation.) (e) is there ever an instant when the velocity is zero? if so, give the time t; if not, answer "0". (f) is there a time after t = 3 s when the particle is moving in the negative direction of x? if so, give the time t; if not, answer "0".
