The final rotational speed ω_final and the instantaneous power P delivered to the wheel are; ω_f = √((ω_i)² + 2(FL/(kmr²) and P = Frω_i
<h3>What is the Instantaneous Power?</h3>
A) From rotational kinematics, the formula for the final angular velocity is;
ω_f = √((ω_i)² + 2αθ)
where;
α is angular acceleration
θ = L/r. Thus;
ω_f = √((ω_i)² + 2α(L/r))
Now, α = T/I
Where;
I is moment of inertia = k*m*r²
T is t o r q u e = F * r
Thus;
α = (F * r)/(kmr²)
α = F/(kmr)
ω_f = √((ω_i)² + 2(F/(kmr))(L/r))
ω_f = √((ω_i)² + 2(FL/(kmr²)
B) Formula for instantaneous power is;
P = Fv
where at t = 0; v = rω_i
Thus;
P = Frω_i

The target heart rate of the 45 year old client with a resting heart rate of 75 bpm is; 135 bpm
Complete question is;
A client is 45 years old and has a resting heart rate of 75 bpm using the karvonen formula what is their target heart rate at an exercise intensity of 60%.
We are given;
Age of client = 45 years
Resting Heart rate = 75 bpm
%Intensity = 60%
The karvonen formula is;
Target Heart Rate = [(max HR − resting HR) × %Intensity] + resting HR
Formula for maximum heart rate is;
Max HR = 220 - age
Max heart rate = 220 - 45
Max HR = 175 bpm
Thus;
Target Heart rate = [(175 - 75) × 0.6] + 75
Target Heart rate = (100 × 0.6) + 75
Target Heart rate = 60 + 75
Target Heart rate = 135 bpm

Answer: The answer is the first one and the last one.
Explanation: If an account cost $1 and each song is 1.5x. It has to be less than or equal to 25. So it would be $1 for (the account plus) 1.5x for (how many songs he buys) is less than or equal to 25 (the ammount on the gift card).
Answer:
Crossing over is a process in meiosis I where chromosomes randomly segregate which ensures both maternal and paternal chromosomes are passed on to each other.
