How to determine the "a" in f=ma or, a=f/m. If a 2200 lb car Is stationary and is struck by a 3300 lb vehicle and is propelled 27 feetfrom the impact? The 3300 lb vehicle had to be traveling how fast?
To determine "a" in the equation f=ma, you need to divide the force (f) by the mass (m). The resulting value is the acceleration (a) of the object.
In the equation f=ma, "a" represents the acceleration of an object, which is the rate of change of its velocity over time. It is a measure of how quickly the object's speed or direction is changing.
The value of "a" is inversely proportional to the mass of an object. This means that as the mass increases, the acceleration decreases, and vice versa. For example, a heavier object will require more force to achieve the same acceleration as a lighter object.
Yes, the equation f=ma can be used to calculate the acceleration of any object, including a car. However, it is important to make sure that the units are consistent. For example, if the mass is given in kilograms, the force should be in Newtons.
To determine the acceleration of a 2200 lb car using f=ma, you first need to convert the mass to kilograms. 2200 lbs is equal to approximately 997.9 kg. Then, you can use the formula a=f/m, where f is the force applied to the car (e.g. by the engine), and m is the mass of the car in kilograms. The resulting value will be the acceleration of the car in meters per second squared.
