please include free body diagrams of each section and explain steps and what has been done. Two Cars A & B having masses of 1,500 kg and 2,000 kg respectively run head-on into each other at C. After the collision, the cars skid with their brakes locked and come to stop in the positions shown in Figure 5. Knowing that the speed of Car A just before the impact was 5 km/h and that the coefficient of kinetic friction between the pavement and the tyres of both cars is 0.3, determine: a) Speed of Car B just before and after the impact and Car A just after the impact. b) Coefficient of Restitution between the two Cars (A & B) and comment on the collision type. VB A B 4 m 1m- C B

Problem 1: Logistic Regression Basics - Odds and Ends a) What is the equivalent odds for the probability 0.25? b) You are testing a new drug and have gathered binary data on whether the drug performed its desired effects. From the control trial, 102 people saw improvement with a placebo and 241 did not. With the drug, 67 people saw improvement and 82 did not. What is the odds ratio of these results? c) You've decided to determine the probability of a picture containing an animal on social media. On 6 different days, you look at 10 random pictures and record the number of pictures that contain at least one animal, and get the values {6,10,7,9,5,9}. Given these results, what is the MLE for the probability of a picture containing an animal?
