Answer:
79.1°
Explanation:
Given:
x₀ = 0 m
y₀ = 0 m
x = 19500 cos 32°
y = 19500 sin 32°
v₀x = 1810 cos 20°
v₀y = 1810 sin 20°
t = 9.20
Find:
ax, ay, θ
First, in the x direction:
x = x₀ + v₀ t + ½ at²
19500 cos 32° = 0 + (1810 cos 20°) (9.20) + ½ ax (9.20)²
16537 = 15648 + 42.32 ax
ax ≈ 21.01
And in the y direction:
y = y₀ + v₀ t + ½ at²
19500 sin 32° = 0 + (1810 sin 20°) (9.20) + ½ ay (9.20)²
10333 = 5695 + 42.32 ay
ay ≈ 109.6
The direction of the acceleration is therefore:
θ = atan(ay / ax)
θ = atan(109.6 / 21.01)
θ ≈ 79.1°
Huh ?!?!?? What does that mean? Can I have brainliest I need one more for my next stage/level
Explanation:
Understanding that stars are naturally quite hot, imagine I pulled a piece of hot iron from a furnace. It would glow a bright red, and then slowly fade to black as the iron cools.
White dwarfs glow for the same reason - they are HOT!
3 seconds (330 m) / second =
990 meter
it's Also called aerobic exercise, endurance exercise includes activities that increase your breathing and heart rate such as walking, jogging, swimming, and biking. Endurance activity keeps your heart, lungs and circulatory system healthy and improves your overall fitness.
