if the distance traveled is over the ground, then you did fine.
I have a question on my assignment paper that I'm unsure if I'm correct. Can someone check it for me please. Thanks.
Q: An aeroplane takes off at an angle of 18 degrees to the level of the ground. It travels a distance of 2,000m in 25 seconds.
A) Sketch a diagram displaying the aeroplane's take off.
B) Find the average speed of the plane, in metres per second.
C) Find the height, h, of the aeroplane above the ground after 25 seconds, correct to the nearest metre.
A) I attached what I think the picture should look like.
B) To get the speed, I put distance over time and got 80 m/sec.
C)To find the height I'm looking for the value of the opposite side of the triangle so I need to get:
Tan of 18 degrees = opp = x
0.3249 ( 2000) = x
x= 649.8 metres
