Question
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 3.90 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 49.3 m/s at an angle of 35 ° 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?
A= 159
WHAT IS B???????
Explanation / Answer
(B)Apply v=u+at along y direction in Earth from initial oiunt to maximum height
0=49.3*sin(35)-(9.8*t) ; t= 2.885 s;
So the total time for the balls motion= 2*t=5.77 s
Apply s=ut horizontally for Earth system
sE=49.3*cos(35)*5.77=233 m
Since range of the ball in planet B(Rb)= 3.9*(range in Earth)
Rb= 3.9*233=908.7m
