Answer:
the train is moving at the speed of v = 1.79 m/s
Explanation:
given,
rain drop is falling vertically down with the speed of = 3.84 m/s
angle of the rain drop = 25°
tan θ = 
tan 25° = 
v =3.84 × tan 25°
v = 1.79 m/s
hence, the train is moving at the speed of v = 1.79 m/s
Answer:
The answer to your question is letter B
Explanation:
Data
Order from fastest to slowest speed
58 72 55 65 70 81 66
The fastest is 81, then, 72, 70, then, 66, 65 finally 58 and 55
The correct order
81 mi/h, 72 mi/h, 70 mi/h, 66 mi/h, 65 mi/h, 58 mi/h, 55 mi/h
The other options are from slowest to fastest or a different order.
