Question

What is the velocity of the object at 9 s ?

A. 0.83 m/s
B. 0.87 m/s
C. 3.3 m/s
D. 5.0 m/s
E. 20 m/$

Answer 1

Without more information, we cannot determine the velocity of the object at 9 seconds.

Step-by-step explanation:

The velocity of an object at 9 seconds can be determined using the kinematics equation v = √vo²+2ad. However, since we do not have the initial velocity or the distance traveled, we cannot use this equation directly. We can use the equation v = vo + at, where vo is the initial velocity, a is the acceleration, and t is the time. Since we do not have the acceleration, we cannot use this equation either. Without more information, we cannot determine the velocity of the object at 9 seconds.
