show complete step-by-step solutions for me to understand the process of solving the problem. 1. A bank robber travelling at 75 mi/h in an escape car suddenly sees s barricade 150 m ahead. The robber slams on the brakes following 0.75-s delay (the driver's reaction time). After the brakes, are applied, the car decelerates at 4.2 m/s2. Will the car hit the barricade and if so, what is its speed/velocity? 2. A rock is thrown down into a well with an initial downward speed of 3.0 m/s. The rock hits the bottom 1.8 seconds later. A.) How deep is the well. B. What is the rock's speed as it hits the bottom
