Complete Question
A 75 kg man and a 100. Kg woman are playing tug of war on a frictionless surface. The man accelerates toward the woman at 2.0 m/s2.How much force does she use to pull on the rope
Answer:
The value is
Explanation:
From the question we are told that
The mass of the man is
The mass of the woman is
The acceleration of the man is
Generally the force which she used to pull the rope is mathematically represented as
=>
=>
The speed of the wave is 40 cm/s
Explanation:
First of all, we start by calculating the frequency of the wave, which is equal to the reciprocal of the period:
where
f is the frequency
T is the period
For the wave in this problem,
T = 0.5 s
So, its frequency is
Now we can find the speed of the wave using the wave equation:
where:
f = 2 Hz is the frequency
is the wavelength
Substituting,

Answer: ≈ 323 m
using Newton's 2nd law, we have:
F = ma
⇒ 5 = 6.a
⇔ a = 5/6 (m/s²)
the work done in 25s is ≈ 323 (m)
