By Tractive Resistances I assume the total driving resistances including air resistance, rolling resistance etc..
In this to move the vehicle at a constant speed the driving force should be equal to tractive resistance.
This means driving force at wheel is 280 N.
Power = Force * Velocity
280 * 18 = 5040 W = 5.04 KW.

Calculate the voltage required to produce a current of 2.0 A in a wire with a resistance of 16?
32v
What do you need to know to be able to determine how far a projectile travels horizontally?
The horizontal velocity of the projectile (and the air resistance if known) will determine the horizontal distance traveled and the time required.
Calculate the voltage of required to push eleven amperes through a 20-ohm resistance?
U = RxI so 11x20=220 volts
A student pushed a box 32.0 m across a smooth horizontal floor using a constant force of 124 N. If the force was applied for 8.00 s how much power was developed to the nearest watt?
First you need to calculate the work required. This is simply force x distance in this case.Once you have that, divide the work by the time.
If a hockey puck is set in motion across a frozen pond if ice friction plus air resistance are neglected the force required to keep the puck sliding at a constant velocity is?
If you have eliminated all resistance then the initial force will be enough.
Is the force required to keep a rocket ship moving at a constant velocity in deep space equal to the ship's weight?
No. Without friction or air resistance, no force is required to keep an object moving at a constant velocity. Also, by the way, just thought we should mention: In deep space, the ship has no weight.
How do you calculate the electromotive force required to push 5 amperes through 22 ohms resistance?
Ok so if you have to take the 5 amperes and multuply them by the 22 ohm resistance giving you the answer of 110 5 * 22 = 110 volts
How do you calculate current required?
By Ohm's Law.... Voltage equals Current times Resistance (V=I*R) So if given the voltage and resistance of a system and applying algebra I=V/R .
Time constant of an RC circuit increases if the value of the resistance is?
Answer : increase The time required to charge a capacitor to 63 percent (actually 63.2 percent) of full charge or to discharge it to 37 percent (actually 36.8 percent) of its initial voltage is known as the TIME CONSTANT (TC) of the circuit. Figure 3-11. - RC time constant. The value of the time constant in seconds is equal to the product of the circuit resistance in ohms and the circuit capacitance in farads. The value of one time constant is expressed mathematically as t = RC.

Why don't you do any work when you carry an object at a constant velocity?
I have no idea why you don't do any work when you carry an object at constant velocity. In a vehicle, you would have rolling resistance and wind resistance. On any other surface, you would have friction. Of course, once you put the object into motion, the energy required to keep it in motion would be less than that required to get it there. Even if you put something into orbit the orbit would slowly decay according to the gravitational section of the Theory of Relativity.
What is required for every graph?
A vertical and a horizontal scales are needed.
