Find the maximum height and the range of the ball.

  • #1

Homework Statement

The acceleration due to gravity on the moon has a magnitude of 1.62m/s^2. Assume that the ball is kicked on the moon instead of on the earth. Find(a) the maximum height H and (b) the range that the ballwould attain on the moon.
acceleration=1.62 m/s^2
H=?
R=?
Vy=0 m/s
Voy=?


Homework Equations


H=-Voy^2/ 2(Ay)



The Attempt at a Solution



Ok I have no Idea what the initial velocity is, so how can I calculate this problem.

Are you sure you've given all the information stated in the question?

Well here's the original question. Review Interactive Learning Ware 2.3 at www.wiley.com/college/cutnell in preparation for this problem. The acceleration due to gravity on the moon has a magnitude of 1.62m/s^2. Assume that the ball is kicked on the moon instead of on the earth. Find(a) the maximum height H and (b) the range that the ballwould attain on the moon.
acceleration=1.62 m/s^2

then it says look at example 6-8 in your book. I know what equation to use, but the question only gives me gravity.

One would need the initial velocity and angle with respect to horizontal.

Otherwise one can only determine the ratios of R and H on the moon with respect to the corresponding R and H on earth, assuming the same initial velocity and angle.

Is there a reference to a similar problem on the earth?

ok in the examples the initial velocity of the football is 14 m/s on earth
