Express your answer in meters per second. Pls show
calculations.
Answer
General guidance
Use the expression of the instantaneous velocity to determine the instantaneous velocity.
Instantaneous velocity is defined as the velocity of an object in motion at the given instant of time. It is denoted by 
.
The expression for the instantaneous velocity is as follows:
Here, 
is the displacement and 
is the change in the time.
The displacement is the difference between the final position and the initial position.
Here, 
is the final position and 
is the initial position.
Step-by-step
Step 1 of 2
The straight-line graph between the displacement and the time represents the uniform velocity of the particle. Thus, the particle will have same velocity at any instant of time. At the instant of time of 10.0 s, the position of the particle is found to be 16.0 m.
The graph is increasing linearly. That is, the velocity is increasing linearly.
Step 2 of 2
Calculate the instantaneous velocity of the particle at time equal to 10.0 s by using the equation as follows:
Substitute 16.0 m for 
, 10.0 m for 
, and 10.0 s for 
.
The instantaneous velocity of the particle at time equal to 10.0 s is equal to 0.60 m/s.
The slope of the displacement versus time graph at the given point gives the value of the instantaneous velocity at that point.
Answer
The instantaneous velocity of the particle at time equal to 10.0 s is equal to 0.60 m/s.
Answer only
The instantaneous velocity of the particle at time equal to 10.0 s is equal to 0.60 m/s.
