Given : The graph of the x-coordinate of a particle going along the x-axis as a function of time
To find : average velocity during 0 to 25 s
Solution
initial position of particle at t = 0 is 0 m
Final Position of Particle at t = 25 is 0 m
Average Velocity = ( Change in Position) / Time
= ( 0 - 0)/(25 - 0)
= 0/0
= 0 m/s
if Graph Show the velocity then to find Distance Covered we need to find
area under Graph
= (1/2) * 10 * 100 + (1/2) * 5(100 + 50) + 50*5 + (1/2)*5*50
= 500 + 375 + 250 + 125
= 1250 m
Average Velocity = 1250/25 = 50 m/s
