Sorry didn't know how to put the dot symbol that's why I put it in parentheses whoopsNascentOxygen said:W = F x v
is not correct
x is not the sign for a dot product
x is the cross product
The symbol mistake was incidental. The major problem is your formula W = F vKararr said:didn't know how to put the dot symbol that's why I put it in parentheses whoops
Edited: it's power=fv.NTW said:Besides, work is not force times velocity...
Edited, p=fvNascentOxygen said:The symbol mistake was incidental. The major problem is your formula W = F v
is not a valid formula. What formula for work does your textbook use?
The maximum speed of a car on a horizontal road depends on several factors such as the engine power, aerodynamics of the car, weight of the car, road conditions, and air resistance.
The maximum speed of a car on a horizontal road can be calculated by using the formula V = √(μmg/ρAC), where V is the maximum speed, μ is the coefficient of friction, m is the mass of the car, g is the acceleration due to gravity, ρ is the air density, A is the frontal area of the car, and C is the drag coefficient.
Air resistance plays a significant role in determining the maximum speed of a car on a horizontal road. As the car moves forward, it encounters air resistance that creates a force in the opposite direction, slowing down the car. This force increases with the speed of the car, and at a certain point, it balances out the driving force of the car, limiting its maximum speed.
The weight of the car affects its maximum speed on a horizontal road as it determines how much force is needed to move the car forward. A heavier car requires more force to overcome its weight, which can limit its maximum speed. On the other hand, a lighter car can achieve a higher maximum speed as it requires less force to move it forward.
The condition of the road surface can affect the maximum speed of a car on a horizontal road. A smooth and well-maintained road offers less resistance, allowing the car to achieve a higher maximum speed. On the other hand, a rough or slippery road surface can increase the resistance and limit the car's maximum speed.
