Im pretty sure the jet airplane is faster
When we set something down on the ground, the kind of work that our arms doing is : negative apex
It's happen whenever we do works that are align with the force of Gravity (to the bottom)
hope this helps
Answer:
17.7 m/s
Explanation:
Given:
y₀ = 0 m
y = 16 m
v₀ = 0 m/s
a = 9.8 m/s²
Find: v
v² = v₀² + 2a (y − y₀)
v² = (0 m/s)² + 2 (9.8 m/s²) (16 m − 0 m)
v = 17.7 m/s
The ball is moving at a speed of 17.7 m/s when it hits the ground.
The ratio would be 1:1 or in other terms the number of protons are equal to the number of neutrons and vice-versa.
To solve this problem it is necessary to use the concepts of Force of a spring through Hooke's law, therefore,

Where,
k = Spring constant
x = Displacement
Initially our values are given,


PART A ) With this values we can calculate the spring constant rearranging the previous equation,



PART B) Since the constant is unique to the spring, we can now calculate the force through the new elongation (0.38cm), that is



Therefore the weight of another person is 265.79N.
