We are interested in the research question: Does the amount of sunlight affect the time it takes for Mimosa pudica to close and reopen their leaves? We collect a random sample of 25 observations that are exposed to light and collect a random sample of 25 observations that are not exposed to light. It is assumed that the two samples are normally distributed with the following sample statistics: Sample Size Mean (in Seconds) Std. Dev. Exposed to Light 25 463.3 239.2 Not Exposed to Light 25 434.12 178.87 Under in this problem, we assume equal variance based off previous research studies.

Q2 (25) Consider two billiard balls of equal mass m and radius r. Ball A moves at velocity $v_A$ and strikes ball B which is at rest. Determine the velocities of the balls after impact if d = 0.7r and the coefficient of restitution is e = 0.6. Neglect friction. Hint: Apply coefficient of restitution equation in the direction of the impact
