which of the accerlation vs time graphs is correct for a book sliding across a horizontal frictionsless table in 1-d at a constant velocity of 3.0 m/s?
Homework Answers
Solution) The area under acceleration time graph gives change in velocity
Here it is mentioned that velocity is constant that is 3m/s
So acceleration should be zero as acceleration a = dv/dt
a = d(3)/dt = 0
So from given graphs it should be graph D

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...

Part 2: Velocity vs. Time 1. For each velocity vs. time graph (Graph 3 and 4), describe how you would walk in order to replicate the 1-D motion graph. Use words such as away, toward, at rest, speeding up, slowing down, constant speed. Be specific with your time periods. 2. For each velocity vs. time graph, create the corresponding position and acceleration versus time graphs. Construct your graph on a computer program such as Microsoft ExcelB. If you do not...

A book slides with initial speed 1.60 m/s across a horizontal table. If it slows to a stop in 0.60 m, what is the coefficient of kinetic friction with the table? Ignore air resistance and assume the acceleration due to gravity is g= 9.8 m/s2.
