An air-track glider is attached to a spring. The glider is pulled to the right and released from rest at t = 0 s. It then oscillates with a period of 2.0 s and a maximum speed of 40 cm/s. a. What is the amplitude of the oscillation? b. What is the glider's position at t = 0.25 s?

A block attached to a spring with unknown spring constant oscillates with a period of 2.00 s. What is the period if a. The mass is doubled? b. The mass is halved? c. The amplitude is doubled? d. The spring constant is doubled? Parts a to d are independent questions, each referring to the initial situation.

A certain viral infection causes a fever that typically lasts 6 days. A model of the fever $\left( \text{in}^{\circ} \mathrm{F}\right)$ on day $x, 1 \leq x \leq 6$ is

$$F(x)=-\frac{2}{3} x^{2}+\frac{14}{3} x+96$$

According to the model, on what day should the maximum fever occur? What is the maximum fever?
