Answer:
A) 17.7 m/s
B) 15.98 m
C) Zero
E) 9.8 m/s²
Explanation:
given information
distance, h = - 34 m
time, t = 5 s
A) What is the initial speed of the egg?
h - h₀ = v₀t - 
t², h₀ = 0
- 34 = v₀ 5 - \frac{1}{2} 9.8 5²
- 34 = 5 v₀ - 122.5
v₀ = 122.5 - 34/5
= 17.7 m/s
B) How high does it rise above its starting point?
v² = v₀² - 2gh
v = 0 (highest point)
2gh = v₀²
h = v₀²/2g
= 17.7²/2 (9.8)
= 15.98 m
C) What is the magnitude of its velocity at the highest point?
v = 0 (at highest point)
E) What are the magnitude and direction of its acceleration at the highest point?
g= 9.8 m/s², since the egg is moved vertically, the acceleration is the same as the gravitational acceleration.
In projectile motion the horizontal component is not affected by gravity. You split the motion in horizontal and vertical motion. The horizontal will be an uniform motion, with v being constant. While the vertical will be an uniform accelerated motion, with the acceleration being the gravity.
The answer is a, series circuit.
True
I hope this helps and have a wonderful day filled with joy!!
Answer:
Explained
Explanation:
Asteroids: Asteroids are generally made up of rocky material, metals and their size are large in comparison to comets. Asteroid belt is found between Jupiter and Mars.
Comets: Comets are made up of ice, dust and rocky material. Generally smaller in size and are far from the Sun. With each orbit nearing the sun ice of the comet vaporize in form of blazing tail.
