y = 3e^(−2x) −5e^(−4x) y'= −6e^(−2x)+20e^(−4x) How do I find the critical point at x? The answer is (1/2)ln(10/3) but I don't know how to get that answer Thank you

Hey, Is there a way to do this question without using integral because I haven't learn any integral yet? I don't know what this equation means $$\int_{T_0}^{T(t)}\frac{1}{u-M}\,du=-k\int_0^t \,dv$$

A cup of tea is removed from the fridge and left on a desk. The temperature of the room is constantly E and T(t) represents the temperature of the tea after t minutes. dT/dt = K(E-T) Z(t) = E-T(t) How do I find the general form of Z and T?

No

Th The formula the teacher gave are p=mv and FT= delta P

No, the question only gave me 50 g bullet and 250J

(Mentor's Note: Thread moved from general physics after being replied to, hence the lack of a template) Find the momentum of a 50g bullet whose kinetic energy is 250J. I know the formula to find momentum is P= mv. Please give me hints
