Question

Problem 57

Answer 1

Given information

Apollo astronauts hit a golf ball on the moon  about .

On Earth same astronaut hit the ball .

The swing, launch angle were the same on moon and earth.

Step-by-step explanation

Step 1.

Let the acceleration  on the moon is and acceleration on the earth is .Given that the launch angle and initial velocity is same at moon and earth so 

  And Let  initial velocity  is at moon and earth.    

Distance at moon is  

Distance at earth is  

From the third equation of motion   , Here   and   represents the final and initial velocities in vertical direction. is acceleration due to gravity and is distance or height.

We are considering the motion in y direction only.

So   

So final velocity will be zero . substituting the values for moon we get
