in 1921, the Dodge Brothers built a boat named the SS Delphine and it had a whopping 3000 HP. So, how much horsepower would a Challenger SRT® Hellcat Redeye Widebody need to tow the SŚ Delphine up the industry standard: Davis Dam Grade Climb?
Pro Tips • Davis Dam assumed grade = 7% • Air density is sea level conditions (.002377 slugs/ft3) w(weight) of the SS Delphine + trailer + Redeye = 3,922,000+ 150,000+ 4451 Lbs • Crr = coefficient of rolling resistance = .015 • Assume Combined CDA is 1555 ft 2 • SAE J2807 (Davis Dam Grande Climb) - min speed is 40mpg (59 ft/s) • F(drag) = 1/2p x V^2 x C(d)A • F(rolling resistance) = W x COS X Crr • F(weight) = W x sin • F(sum) = F(drag) + F(rr) + F(weight) • P = F(sum)XV • convert to horsepower = P(1hp/550ft lbf/sec)

Is posible that you put all the procedure step by step?, thank!!!!
To calculate the amount of horsepower the Challenger SRT Hellcat Redeye Widebody would need to tow the SS Delphine up the Davis Dam Grade Climb, we need to consider several factors and use the given formulas.
1. Calculate the total weight: Add the weight of the SS Delphine (3,922,000 lbs), the weight of the trailer (150,000 lbs), and the weight of the Redeye Widebody (4,451 lbs). The total weight is 4,076,451 lbs.
2. Calculate the drag force (F(drag)): Use the formula F(drag) = 0.5 x p x V^2 x C(d)A, where p is the air density (0.002377 slugs/ft^3), V is the velocity (59 ft/s), C(d) is the drag coefficient, and A is the cross-sectional area (1555 ft^2) of the vehicle.
3. Calculate the rolling resistance force (F(rolling resistance)): Use the formula F(rolling resistance) = W x cos x Crr, where W is the weight (4,076,451 lbs), cos is the slope of the grade (7%), and Crr is the coefficient of rolling resistance (0.015).
4. Calculate the weight force (F(weight)): Use the formula F(weight) = W x sin, where W is the weight (4,076,451 lbs) and sin is the slope of the grade (7%).
5. Calculate the sum of the forces (F(sum)): Add F(drag), F(rolling resistance), and F(weight) to get F(sum).
6. Calculate the power required (P): Use the formula P = F(sum) x V, where P is the power required and V is the velocity (59 ft/s).
7. Convert power to horsepower: Divide P by 550 ft lbf/s to convert it to horsepower.
By following these steps and plugging in the given values, you can calculate the amount of horsepower the Challenger SRT Hellcat Redeye Widebody would need to tow the SS Delphine up the Davis Dam Grade Climb according to the provided industry standards.
