Mark appropriate equally-spaced time intervals on the x-axis so that you can easily graph the time values from the table. Step 4 Mark appropriate velocity increments on the y-axis so that you can easily graph the velocity values from the table. If you have negative velocity values, extend ...
【题目】T he figure shows a velocity-time graph for the motion of a particle in a straight line.(1)Find the displacement of the particle at times t=40, t=80, t=120 and t=200.(2)Find the total distance travelled.(3)At what time does the particle pass its starting point?

The area under a velocity-time graph is the distance travelled. The graphbelow shows the relationship v= t2 for the first 3 seconds of motion for abody moving from rest.v(ms^(-1))A3t (seconds)Find the shaded area, and hence the distance travelled (in metres), duringthe first 3 secon...
travelling in a straight line with velocity ms-1 at time s. The particle accelerates at ms-2 for the first s of its motion and then travels at constant velocity, for s. The particle then decelerates at a constant rate and comes to rest. The distance travelled during the interval...
