Question

What is the change in speed when an object accelerates from 2.4 m/s to 3.4 m/s in 3.6 seconds?

a) 0.1 m/s
b) 1.0 m/s
c) 1.4 m/s
d) 2.0 m/s

Answer 1

The change in speed when an object accelerates from 2.4 m/s to 3.4 m/s in 3.6 seconds is 1.0 m/s, corresponding to option b).

Step-by-step explanation:

This is asking for the change in speed of an object that accelerates from 2.4 m/s to 3.4 m/s over a period of 3.6 seconds. To find the change in speed, we subtract the initial speed from the final speed: Change in speed = Final speed - Initial speed, Change in speed = 3.4 m/s - 2.4 m/s = 1.0 m/s. Therefore, the change in speed is 1.0 m/s, which corresponds to option b). his indicates that the object's speed increased by 1.0 meters per second over the given time frame. Such problems exemplify the fundamental principles of kinematics, showcasing how to analyze and quantify the motion of objects undergoing acceleration in a straightforward manner.
