Chapter 18, Problem 23ICA

If an object is heated, the temperature of the body will increase. The energy (Q) associated with a change in temperature (ΔT) is a function of the mass of the object (m) and the specific heat(Cp). In an experiment, heat is applied to the end of an object, and the temperature change at the other end of the object is recorded. This leads to the following equation.

     Δ T = Q m C p

An unknown material with a mass of = kilograms is tested in the lab, yielding the following results. Use the polyfit function to determine the specific heat of this material and store the final result in the variable Cp.

Create a proper plot of the data. Add a linear trendline, showing the resulting trend line equation, on the graph for a change in temperature over a range of energy from 5 joules to 70 joules.

An object attached to a spring undergoes simple harmonic motion modeled by the differential equation d²x = 0 where x (t) is the displacement of the mass (relative to equilibrium) at time t, m is the mass of the object, and k is the spring constant. A mass of 3 kilograms stretches the spring 0.2 meters. dt² Use this information to find the spring constant. (Use g = 9.8 meters/second²) m k = + kx The previous mass is detached from the spring and a mass of 17 kilograms is attached. This mass is displaced 0.45 meters below equilibrium and then launched with an initial velocity of 2 meters/second. Write the equation of motion in the form x(t) = c₁ cos(wt) + c₂ sin(wt). Do not leave unknown constants in your equation. x(t) = Rewrite the equation of motion in the form ä(t) = A sin(wt + ), where 0 ≤ ¢ < 2π. Do not leave unknown constants in your equation. x(t) =
