Lesson: Acceleration over a Distance Physics • 9th Grade
In this lesson, we will learn how to use an object’s initial and final velocities and the object’s displacement to define acceleration by using the formula v² = u² + 2as.
An object has an initial velocity that increases to 14 m/s as the object accelerates at 5 m/s2 in the direction of its velocity. The object accelerates along a 17.1 m long straight line. What is the object’s initial velocity?
An object has an initial velocity of 6 m/s and accelerates in the direction of its velocity along a 16 m long straight line at a rate of 2 m/s2. What final velocity does the object have?
An object starts from rest and accelerates at 2 m/s2 along a 9 m long straight line. What final velocity does the object have?
