  1. The airborne time will be given by:

    t = v1/g where t is the time taken, v1 is the initial velocity and g is the acceleration due to the gravity pulling the golf ball towards the center of the earth.

    t=60/9.8
    t=6.12244897959 seconds.

    Multiplying that by 2 to have the total airborne time,

    actual time = 12.2448979592 seconds.

    Now, for the horizontal distance traveled,

    Using simple height and distance, if the golf ball covered a distance of 60 meters in one second at an angle of 65° then the horizontal distance covered must be 25.3570957044 meters.

    Multiplying that by the airborne time, we have,

    25.3570957044 * 6.12244897959
    = 155.247524721 meters.

    So the golf ball was in the air for 6.1 seconds and the horizontal distance covered was 155.2 meters.
