Forces
The Aston Martin One-77 has an average mass of 3307 lbs (1500 kg) (9)
The Aston Martin One-77 has a uniform acceleration from rest of 7.6 m/s2
If, after travelling for 100 m, an Aston Martin One-77 acquires a speed of 38.9 m/s, what is the horsepower of the car? Since we know that a Aston Martin One-77 has a 750 horsepower engine, from this calculation, we may be able to determine how much horsepower is lost in the transmission of the car (from the engine to the transmission finally to the wheels)
Step 1: In this step, we use Newton's Second Law to calculate the force, in Newtons, that the car will exert
Step 2: Using force, we can determine Work in Joules by plugging in our given value of distance (100 m)
Step 3: Here we find out, based on the speed of the car, how long it would take for the vehicle to travel 100 m. We re-arrange the formula for speed (V=d/t) to find time in seconds
Step 4: We can find the power of the car in Watts with our new time value because we already have work and time in seconds.
Step 5: Finally, we convert the power of our car in Watts into horsepower, since 1 hsp is equal to 746 Watts.
We can conclude from our results above that approximately 155 horsepower (750 - 594.61 = 155.39) is lost between the Aston Martin One-77's engine and the wheels.
Step 1: Using Newton's Universal Law of Gravitation, we can plug in all our known values (as well as the Universal Constant G) to obtain the gravitational force in Newtons pulling our two cars together
