The sine of the angle (25°) of a right triangle is defined as the opposite cathetus () to that angle divided into the hypotenuse (W):
The cosine of the angle (25°) of a right triangle is defined as the adjacent cathetus () to that angle divided into the hypotenuse (W):
Recall that the maximum frictional force is defined as:
Replacing (3) in (1) and (4) in (2):
Replacing (7) and (6) in (5) and solvinf for :
7 and a half hours because if you multiply 120 by 8 you get 960 and if you multiply 120 by 7 you get 840. So it’ll take 7 full hours and 30 minutes to reach 950 km. Hope this helps and I’m sorry if it’s wrong I did my best :)
