    How Does a Pitcher's Force Influence a Baseball's Acceleration and Distance?

    Ok - so if the ball starts at rest, the acceleration is zero, and the distance is zero because it is still in the pitchers hand. I think?

    How Do You Calculate Radial Acceleration at the Equator Due to Earth's Rotation?

    thanks so much!

    How Do You Calculate Radial Acceleration at the Equator Due to Earth's Rotation?

    w=2pi/86400sec w=0.00007 0.00007(6370km)=0.46324km/sec vt=0.46324km^2/6370 vt=0.0000336 Thats what i get, what am i doing wrong?

    How Do You Calculate Radial Acceleration at the Equator Due to Earth's Rotation?

    Would that be the period T, where that is the time to complete one revolution? T=2pi(r)/v

    How Does a Pitcher's Force Influence a Baseball's Acceleration and Distance?

    Sorry! I know that gravitational force is Fg=mg And Vxf=Vxi + axt for constant a

    How Do You Calculate Radial Acceleration at the Equator Due to Earth's Rotation?

    Sorry! I know that centripetal acceleration is v^2/r The diameter of the Earth is 12740 km, and half of that is the radius of 6370km. How would I find v?

    How Do You Calculate Radial Acceleration at the Equator Due to Earth's Rotation?

    Knowing that the diameter of the Earth at the equator is 12 740 km, compute the radial acceleration of a point on the surface of the Earth at the equator, due to the rotation of the Earth about its axis.

    How Does a Pitcher's Force Influence a Baseball's Acceleration and Distance?

    The gravitational force on a baseball is −Fgjˆ. A pitcher throws the baseball with velocity viˆ by uniformly accelerating it straight forward horizontally for a time interval ∆t =t–0 = t. If the ball starts from rest, (a) through what distance does it accelerate before its release? (b) What...
