Help l Announcements Assignment en Assignment PRINTER VERSION ACK NEXT Chapter 03, Problem 34 Interactive LearningWare 3.2 provides a review of the concepts that are important in this problem. On a distant planet, golf is just as popular as it is on earth. A golfer tees off and drives the ball 3.60 times as far as he would have on earth, given the same initial velocities on both planets. The ball is launched at a speed of 40.5 m/s at an angle of 30 o above the horizontal. When the ball lands, it is at the same level as the tee. On the distant planet, what are (a) the maximum height and (b) the range of the ball? units (a) Number (b) Number Units Click if you would like to show Work for this questi Open Show Work Question Attempts: Unlimited SAVE FOR LATER SUBMIT ANSWER Copyright D 2000-2017 by ohn Wiley & Sons, Inc. or related companies.

Explanation / Answer

b)We use projectile motion formulae,

Rplanet = 3.60*Rearth

Range on earth = Rearth = (v02sin2)/gearth = (40.5^2*sin(2*30))/9.8 = 144.95 m

Range on earth = Rearth = Rplanet = 3.60*Rearth = 3.60*144.95 = 521.8 m

gplanet /gearth = Rearth/Rplanet

gplanet = [gearth*( Rearth/Rplanet)] = [9.8*(1/3.60)] = 2.72 m/s^2

a)

Maximum height = H = (v02sin2)/2gearth = (40.5^2*(sin30)^2)/(2*9.8) = 20.9 m
