 The range R of the ball refers to how far it moves horizontally, from just after it is launched until just before it lands. Range is defined as x2âˆ’x0, or just x2 in this particular situation since x0=0.

Here is the answer for the question - The range R of the ball refers to how far it moves horizontally, from just after it is launched until just before it lands. Range is defined as x2âˆ’x0, or just x2 in this particular situation since x0=0.. You'll find the correct answer below

The range R of the ball refers to how far it moves horizontally, from just after it is launched until just before it lands. Range is defined as x2âˆ’x0, or just x2 in this particular situation since x0=0. Part E Which of the following changes would increase the range of the ball shown in the original figure? Check all that apply. -Increase v0 above 30 m/s. -Reduce v0 below 30 m/s. -Reduce Î¸ from 60 degrees to 45 degrees. -Reduce Î¸ from 60 degrees to less than 30 degrees. -Increase Î¸ from 60 degrees up toward 90 degrees.

Increase v0 above 30 m/s.Reduce Î¸ from 60 degrees to 45 degrees.(A solid understanding of the concepts of projectile motion will take you far, including giving you additional insight into the solution of projectile motion problems numerically. Even when the object does not land at the same height from which is was launched, the rules given in the introduction will still be useful.Recall that air resistance is assumed to be negligible here, so this projectile motion analysis may not be the best choice for describing things like frisbees or feathers, whose motion is strongly influenced by air. The value of the gravitational free-fall acceleration g is also assumed to be constant, which may not be appropriate for objects that move vertically through distances of hundreds of kilometers, like rockets or missiles. However, for problems that involve relatively dense projectiles moving close to the surface of the earth, these assumptions are reasonable.)
