In this question we are given that acceleration due to gravity on the moon is g by 6.
00:05
That means 9 .81 divided by the 6.
00:09
It will have a value of 1 .635 meter per second square.
00:17
Now if this projectile or we can say the golf is heated at an angle of 36 degree with 30 meter per second speed.
00:30
And we want to calculate that how long will this goal be in the air and how long? long will it travel.
00:37
So the time of flight would be as we calculated in our classes, it is coming out with 2 u .s, sine theta by g.
00:45
You can derive this formula also, taking the vertical component to the velocity that would be 30 sine theta.
00:51
All right.
00:52
And acceleration due to gravity in the vertical direction is downward.
00:55
That is whatever the acceleration g was right.
00:58
So the velocity will go up, then we'll come back downwards...
