Two bodies are colliding with each other. Assuming that the bodies have initial velocities on the same axis, what are the final velocities of the bodies if the collision is totally inelastic. What are the velocities if the collision is totally elastic? This is the problem, there are multiple cases based on the sense of initial velocities and mass i think but i dont know what those are please help

An insurance company wants to know if the average speed at which men drive cars is higher than that of women drivers. the company took a random sample of 27 cars driven by men on a highway and found the mean speed to be 72 miles per hour with a standard deviation of 2.2 miles per hour. another sample of 18 cars driven by women on the same highway gave a mean speed of 68 miles per hour with a standard deviation of 2.5 miles per hour. assume that the speeds at which all men and all women drive cars on this highway are both approximately normally distributed with unknown and unequal population standard deviations.
