• Now, let's do the numbers. Let's assume the person (me) can througha stone at 25% of a good baseball pitcher throwing a baseball, whichwould make it 11 m/s. Let's call the distance the stone has been thrownto be 25 yards, which makes it 23 meters. Solve for the average accel-eration experienced by the stone. How much is it? (State in m/s? AND infractions of g)• and finally, which FORCE causes that acceleration? (or rather deceler-ation) Hint: NOT gravity, because gravity acts vertically, and we agreedthat the x and y dimensions are independent, so a force that causes achange of state of motion in the HORIZONTAL direction cannot be grav-ity. • We learned the set of 1D-Kinematic equations that describe the Uni-formly Accelerated Motion to be structured as "position as a function oftime", "velocity as a function of time", and acceleration = constant.It is possible with some maths to make an equation WITHOUT time that re-lates jsut the distance traveled, the uniform acceleration and the speedat the beginning at the end.This equation is:2 ad = v – vố(1)where a is the said acceleration, d is the distance, and vo and vf are theinitial and the final speed respectively. For an alternative notation followthe link: 1D-Kinematics The point of this homework is not to learn a newequation, but to practice equation properties in a new format.• State the units on the LHS and the RHS. Do they match up?• As you see the person (me) throwing the stone how much is the FINALvelocity? Restate the equation (1) with that information mind:• If you did everything right then you end up with your RHS NEGATIVE (!).That means that the LHS must also be negative. How can that be?Which term (letter) is negative on the LHS?? Does that make sense?Why or why not?1
