Here is a plot of velocity versus time for a particle that travels along a straight line with a varying velocity. Refer to this plot to answer the following questions. Part A What is the initial velocity of the particle, ? Express your answer in meters per second. =0.5 Correct Part B What is the total distance traveled by the particle? Express your answer in meters. =75 Correct Part C What is the average acceleration of the particle over the first 20.0 seconds?

Express your answer in meters per second per second. =0.075 Correct The average acceleration of a particle between two instants of time is the slope of the line connecting the two corresponding points in a v vs. t graph. Part D What is the instantaneous acceleration of the particle at ? = 1 0.20 -0.20 0.022 -0.022 Correct The instantaneous acceleration of a particle at any point on a v vs. t graph is the slope of the line tangent to the curve at that point. Since in the last 10 seconds of motion, between and , the curve is a straight line, the tangent line is the curve itself. Physically, this means
