This Question: 1 pt Skid mark analysis is one way to estimate the speed a car was traveling prior to an accident. The speed, that the vehicle was traveling in mies per hour can be approximated by the formula 330df, where d represents the length of the skid marks in feet and represents the drag factor of the road. A vehicle that was involved in an accident on an asphalt road was traveling ata speed of 75 mph when it...

(20 points) A car starting from rest travels 220 m in 9.4 seconds with a constant acceleration. It then travels at a constant speed for another 12 seconds. After that, the brakes are applied and the car comes to rest an acceleration of 6.5 m/s2. A) Draw the motion diagram for the entire trip. B) What direction is the acceleration when the car is coming to rest? C) List all known variables with their values. D) What is the acceleration...

1. A car starts from rest and travels for 8.0 s with a uniform acceleration of +1.8 m/s2. The driver then applies the brakes, causing a uniform acceleration of −1.5 m/s2. If the brakes are applied for 2.0 s, determine each of the following. (a) How fast is the car going at the end of the braking period? (m/s) (b) How far has the car gone? (m) 2. A ball is hit with a paddle, causing it to travel straight...

A speeder traveling at a constant speed of 99 km/h races past a billboard. A patrol car pursues from rest with constant acceleration of (9 km/h)/s until it reaches its maximum speed of 161 km/h, which it maintains until it catches up with the speeder. How long does it take the patrol car to catch the speeder if it starts moving just as the speeder passes? Answer in units of s. How far does each car travel? Answer in units...
