Yes. I think it is. If you are wasting your time staring at a wall, but you are enjoying it and still have work to do, you are wasting your time. Sometimes the point of wasting time is to, well waste time, but that doesn’t change the fact that you are wasting your time.
1. the positioning of the sun
2. equinox
3. summer solstice
Answer:
A ruler in centimeters and/or inches.
Explanation:
This is the most convenient option to measure a soda can.
Ok so use trigonometry to work out the vertical component of velocity.
sin(25) =opp/hyp
rearrange to:
30*sin(25) which equals 12.67ms^-1
now use SUVAT to get the time of flight from the vertical component,
V=U+at
Where V is velocity, U is the initial velocity, a is acceleration due to gravity or g. and t is the time.
rearranges to t= (V+u)/a
plug in some numbers and do some maths and we get 2.583s
this is the total air time of the golf ball.
now we can use Pythagoras to get the horizontal component of velocity.
30^2-12.67^2= 739.29
sqrt739.29 = 27.19ms^-1
and finally speed = distance/time
so--- 27.19ms^-1*2.583s= 70.24m
The ball makes it to the green, and the air time is 2.58s
