Sure I will give two examples
Application of tangents
1. If we are traveling in a car around a corner and we drive over something slippery on the round ( like water , ice or oil ) , our car starts to skid
It continue in a direction tangent to the curve
Application of tangents
2. Have you ever sat on a merry- go around
If yes , then you would understand
From your experience when I tell you that the force your experience is towards the centre of merry- go around but your velocity ( the tendency of motion) is in the way toward which your body pointing
Another way saying the same thing would be to let you know that your velocity at any point is tangent while force .
At any point is normal to the circle along which you are moving
Can you draw connection between both the ways of saying the same thing?
Have this two example help you
Good luck :D
Answer:
Step-by-step explanation:
Let the speed of the car is x, then the speed of motorcycle is x + 20
The distance = 120 km
<u>Time:</u>
- 120/x = 120/(x + 20) + 1
- 120(x + 20) = 120x + x(x +20)
- 120x + 2400 = 120x + x² + 20x
- x² + 20x = 2400
- x² + 2*10x + 10² = 2500
- (x + 10)² = 50²
- x + 10 = 50
- x = 40
Speed of the car is 40 km/h
Speed of the motorcycle is 60 km/h
Answer:
56.4 degrees
Step-by-step explanation:
90 degrees - 33.6 degrees = 56.4 degrees
