Where is the projectile at 10 seconds after firing?
At t=10 seconds, the projectile is at (1061 m, 571 m) or 1061 m downrange and at an altitude of 571 meters.
Is F MA multiple choice?
You may not use any tables, books, or collections of formulas. This test contains 25 multiple choice questions. Your answer to each question must be marked on the optical mark answer sheet that accompanies the test.
How do you calculate acceleration using F MA?
- According to Newton’s second law of motion, the acceleration of an object equals the net force acting on it divided by its mass, or a = F m .
- This equation for acceleration can be used to calculate the acceleration of an object when its mass and the net force acting on it are known.
How do you calculate projectile?
Projectile motion equations
- Horizontal velocity component: Vx = V * cos(α)
- Vertical velocity component: Vy = V * sin(α)
- Time of flight: t = 2 * Vy / g.
- Range of the projectile: R = 2 * Vx * Vy / g.
- Maximum height: hmax = Vy² / (2 * g)
How do you prove F MA in an experiment?
To show that F=ma you will first have to define what you mean with a force and than show that that when you increase the force that than the acceleration increases with the same factor if you do not change the mass. You can also show that when you double the mass de acceleration halves.
What is F MA used for?
Newton’s second law is often stated as F=ma, which means the force (F) acting on an object is equal to the mass (m) of an object times its acceleration (a). This means the more mass an object has, the more force you need to accelerate it. And the greater the force, the greater the object’s acceleration.
What three factors affect the amount of air resistance on an object?
The amount of air resistance an object experiences depends on its speed, its cross-sectional area, its shape and the density of the air.
Why f MA is the most important equation in physics?
If you can measure the mass of your object and how it’s accelerating, you can use F = ma to determine the net force acting on the object. If you can measure the mass of your object and you know (or can measure) the net force being applied to it, you can determine how that object will accelerate.
