Answer:
429 m
Explanation:
In this exercise you are suppose to simulate a right triangle, the catheti are the distance you walked and the height of the empire state building.
tan(88) = (height) /(distance you walked)
28.64 = height / 15
height = 429 m

Answer:
my favourite song is hym to the sea. That song reminds me of the innocent people who lost their lives in titanic a century ago. If I was the writer of that song ,i would not change the title of that song because I can feel the sound of ocean when I listen to that song.
Explanation:
Using kinematics,
t = 10s
v = 0m/s
a = -9.8m/s^2
Therefore u = v - at = 0 - (-9.8)(10) = 98m/s.
Answer:
P = 6000 W
Explanation:
The given question is "The motor of a motorcycle gives it a speed of 90 km / h when a force of 240 N is applied to it. What is the power of the motorcycle in watts?"
Given that,
Speed of a motorcycle, v = 90 km/h = 25 m/s
Force applied to the motorcycle, F = 240 N
We need to find the power of the motorcycle. We know that,
Power = Fv
So,
P = 240 N × 25 m/s
= 6000 W
So, the required power of the motorcycle is equal to 6000 W.
