Explain how the mass of your race car will affect its performance in reference to Newtons 2nd law of motion. Use the terms force, mass, and acceleration. I need help ASAP!!

Determine the maximum r-value of the polar equation r =3+3 cos 0

If y gets smaller as x gets bigger and y have an relationship?

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".
