Speed = (distance covered) / (time to cover the distance)..
From the ground to the highest point,
the rocket's AVERAGE speed is
(86 m) / (3.7 sec) = 23.2 m/s (rounded) .
Answer:
During a lunar eclipse, the Moon turns red because the only sunlight reaching the Moon passes through Earth's atmosphere. The more dust or clouds in Earth's atmosphere during the eclipse, the redder the Moon will appear.
Her magnitude of deceleration on the ice would be 15.126m/s
Answer:

Gina should put “starch” under “Natural.”
Explanation: I just did the assignment ;P
Refer to the diagram shown below.
In 2.4 hours, the distance traveled by the first airplane heading a 51.3° at 750 mph is
a = 750*2.4 = 1800 miles.
The second airplane travels
b = 620*2.4 = 1488 mile
The angle between the two airplanes is
163° - 51.3° = 111.7°
Let c = the distance between the two airplanes after 2.4 hours.
From the Law of Cosines, obtain
c² = a² + b² - 2ab cos(111.7°)
= 3.24 x 10⁶ + 2.2141 x 10⁶
c = 2335.41 miles
Answer: 2335.4 miles
