Get started for freeMake a position-time graph for a particle that is at \(x=3.1 \mathrm{~m}\) at \(t=0\) and moves with a constant velocity of \(-2.7 \mathrm{~m} / \mathrm{s}\). Plot the motion for the range \(t=0\) to \(t=6.0 \mathrm{~s}\).
Triple Choice You travel along the \(x\) axis from the location \(x_{\mathrm{i}}=10 \mathrm{~m}\) to the location \(x_{\mathrm{f}}=25 \mathrm{~m}\). Your location \(x_{\mathrm{i}}=10 \mathrm{~m}\) to the location \(x_{\mathrm{f}}=25 \mathrm{~m}\). Your friend travels from \(x_{\mathrm{i}}=35 \mathrm{~m}\) to \(x_{\mathrm{f}}=40 \mathrm{~m}\). Is the distance you cover greater than, less than, or equal to the distance covered by your friend? Explain.
(a) What is the velocity of an object that moves from \(73 \mathrm{~m}\) to \(62 \mathrm{~m}\) in \(12 \mathrm{~s}\) ? (b) What is its speed?
Is it possible for two different objects to have the same speed but different velocities?
