    Instantaneous Acceleration from a Velocity-Time graph

    Hey BvU, Thanks for the welcome! My answers varied as I tried quite a few different tangent lines for each point. I was able to get an instantaneous accelerations of 3.5 m/s/s and ~3.0 at 9 s, 1.5 m/s/s and ~1.33 m/s/s at 13 s, and of course 0 m/s/s at 15 s. @Chestermiller Is finding the...

    Instantaneous Acceleration from a Velocity-Time graph

    Homework Statement [FONT=Verdana]A test driver is testing a new model car with a speedometer calibrated to read m/s rather than mi/h. The following series of speedometer readings were obtained during a test run along a long, straight road: [FONT=Courier New]Time (s): 0 2 4 6 8 10 12 14 16...

    [Basic Velocity] Finding velocity with x and y distances?

    Ex. problem. A plane is flying 140m above the surface. A parachutist drops out of the plane and lands 60m from where he jumped out. What is the plane's velocity? I used the Pythagorean theorem to find the displacement of the parachutist, i.e. the hypotenuse. I then multiplied the parachutist's...
