P = mv
p = (1600kg)(20m/s)
p = 32000 N
(3.2x10^4 N)
Answer:
as space stretches, the waves of radiation in space also stretch and their wavelength increases
Explanation:
Answer:
The answer to your question is
a) t = 2.55 s
b) t = 5.5 s
Explanation:
Data
vo = 25 m/s
h = 2 m
g = 9.81 m/s
Formula
t = -(vo)/g
a)
t = -(25)/9.81
t = 2.55 s
b)
Tt = 2t
Tt = 2(2.55)
Tt = 5.1 s
Time in the last 10 m
10 = 25t + (1/2)(9.81)t²
Simplify
10 = 25t 4.91t²
4.9t² + 25t - 10 = 0
Solve the equation using an online calculator
t₁ = 0.37 s t₂ = -5.47 s
The correct answer is t₁, t₂ is incorrect because there are no negative answers.
Total time = 5.1 + 0.37
= 5.5 s
To answer this question, we need to find the force acting on the two objects.
f=ma
f=(6)(2)
f=12 newtons
So, now we can determine the acceleration of the second object using the same formula!
f=ma
12=(4)a
3=a
So the acceleration of the smaller object is 3 meters per second squared!
