Engineering Mechanics Dynamics · R.C. Hibbeler · Chapter 12

Course: Engineering Mechanics Dynamics Book: R.C. Hibbeler Chapter: Chapter 12

Question

Question:
A sphere is fired downwards into a medium with an initial speed of 27 meters per second. It experiences a deceleration given by a equals negative 6t meters per second squared, where t is time in seconds. Determine the total distance traveled before the sphere stops.


Kinematics with Variable Acceleration: Finding Distance Traveled

This lesson applies integral calculus to a kinematics problem involving a time-dependent (variable) deceleration. Students integrate acceleration to find velocity, determine when the object stops, and integrate velocity to compute total distance traveled.

In this lesson, you will learn to:
• Integrate a variable acceleration function to obtain a velocity function using an initial condition
• Determine the time at which an object's velocity reaches zero by solving the resulting equation
• Verify that velocity does not change sign over the interval o
