A student measures the velocity of an object moving along a track. At time t = 0 s, the object is moving at a constant 4.0 m/s in the positive x-direction. At time t = 3.0 s, the object begins to slow, stops at t = 5.0 s, and then moves in the opposite direction. At t = 6.0 s, the object as reached a speed of -2.0 m/s. It moves at this speed until the student quits taking data...

Which of the following situations is impossible? An object has velocity directed cast and acceleration directed west. An object has velocity directed cast and acceleration directed east. An object has zero velocity but non-zero acceleration. An object has constant non-zero acceleration and changing velocity. An object has constant non-zero velocity and changing acceleration. An object is thrown upwards with a speed of 16 m/s. How long does it take it to reach a height of 7.0 m on the way...

With details please
An object with a mass of 4.25 kg undergoes an acceleration of 3.7 m/s^2 for a period of 8.0 s. If the initial velocity of the object is -7.05 m/s and it first experiences the acceleration when it is at the origin, plot by hand on graph paper (to scale) the force, velocity, and position as functions of time. Explain why your graphs look the way they do. Include all relevant equations.

What Velocity vs. Time Graphs Can Tell You Constants A common graphical representation of motion along a straight line is the v vs. t graph, that is, the graph of (instantaneous) velocity as a function of time. In this graph, time t is plotted on the horizontal axis and velocity v on the vertical axis. Note that by definition, velocity and acceleration are vector quantities. In straight-line motion, however, these vectors...
