Each of the following parts of Problem 1 refers to the same vehicle. Assume aerodynamic drag is zero, friction force on each of the four tires is equal, and the vehicle can be modeled as a particle. Also, assume it has modern traction control so the tires never actually slip and kinetic friction coefficient is irrelevant. a. Determine the distance travelled for the vehicle stopping on dry pavement from 30 mph to zero in 2.0 seconds. Assume acceleration is constant and provide your final answer in feet. b. Determine coefficient of friction for part a. Provide a supporting FBD. c. Determine the distance travelled from 30 mph to zero if the vehicle is on a snow covered road with coefficient of static friction = 0.10. Assume deceleration is constant and provide your final answer in feet. d. Use the coefficient of friction from part b to determine maximum tangential velocity on a 200-foot diameter skid pad. Provide your final answer in mph. e. Determine the minimum radius curve that the vehicle can successfully navigate at 30 mph if the curve is snow covered with static friction coefficient = 0.10. Give your final answer in feet and provide a supporting FBD.
Displacement, Velocity and Acceleration
In classical mechanics, kinematics deals with the motion of a particle. It deals only with the position, velocity, acceleration, and displacement of a particle. It has no concern about the source of motion.
Linear Displacement
The term "displacement" refers to when something shifts away from its original "location," and "linear" refers to a straight line. As a result, “Linear Displacement” can be described as the movement of an object in a straight line along a single axis, for example, from side to side or up and down. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Linear displacement is usually measured in millimeters or inches and may be positive or negative.
