Starting from rest, the plane travels a distance
<em>x</em> = 1/2 <em>at</em>²
with acceleration <em>a</em> after time <em>t</em>. In this instance, it travels
<em>x</em> = 1/2 (3.20 m/s²) (32.8 s)²
<em>x</em> ≈ 1720 m
Answer:
V = 3.97 m/s
Explanation:
Mass of a man, M = 85 kg
Mass of a bullet, m = 8 g = 0.008 kg
Speed of bullet, v = 410 m/s
We need to find the speed of a man in order to have the same kinetic energy as that of the bullet. Let the kinetic energy of the bullet is k. So,
Since, k = K (K is the kinetic energy of the man and Let V is the speed)
So, the speed of the man is 3.97 m/s.
Answer:
Maximum height, H = 35 meters
Explanation:
Given the following data;
Time = 7 seconds
Acceleration due to gravity, g = 10 m/s²
To find the maximum height;
Mathematically, the maximum height is given by the formula;
H = ½gt²
H = ½ * 10 * 7
H = 5 * 7
Maximum height, H = 35 meters
Answer:
The two people would fall down according to the laws of physics by Sir Issac Newton
Explanation:
Also write this (according to my unit I teach to my kids since I am a teacher but don't tell anyone): Just like if an apple were to fall, the tree would go upwards and the apple would fall. :)
