Find x and y in the following figure
Answers
Step-by-step explanation:
180 km/h = 50 m/s when the plane started its take off by following the indicated path. Once it reaches the point labelled 1000 m it had climb that said height. Its speed is uniform so the path length is equal to speed * time or 50 m/s * time. The sine of the angle of 32º is equal to altitude over the path length.
In formula form the path length is sine 32º * speed * time. The time is solved by using time = 1000 m / (speed * sin32º). Solving for the time of rise
time = 1000 m÷(50 m/s × 0.5299)
time = 37.74 seconds and the path length = 50 m/s * 37.74 s or a displacement of 1887 meters
Step-by-step explanation:
Ques 1: A farmer moves along the boundary of a square field of side 10 m in 40 s. What will be the magnitude of displacement of the farmer at the end of 2 minutes 20 seconds?
Ans: Distance covered in one round = 40 m
Time taken = 40s
Total time of journey = 2 min. 20s = 140 s
Total distance covered = = 140 m
Total rounds = = 3.5 round
After every complete round, the farmer will be at the starting point, hence after 3.5 rounds farmer will be at the diagonal ends of the field.
Displacement = 10√2m
