How do you find the acceleration of a catapult?
For example, a distance of 100 meters at 10 seconds is: vh = 100/10 = 10 m/s. So, if the projectile took 5 second to reach maximum height: vv = (9.8)(5) = 49.4 m/s.
How do you find the equation of a catapult?
Equations
- Height = ( v sinθ )² / 2g.
- Time of flight = 2 v sinθ / g.
- Range or horizontal distance covered = v² ( sin 2θ ) / g.
- assumes zero loss.
How do you calculate the projectile motion of a catapult?
Projectile Motion
- Equation 1: df=di+vit+12at2.
- Equation 2: vf=vi+at.
- Equation 3: v2f=v2i+2a(df−di)
- Equation 4: df=di+12(vf+vi)t.
- Equation 5: x(t)=x0+vx,0t+12axt2.
- Equation 6: x(t)=vx,0t.
- Equation 7: vx,0=v0cos(θ) v x , 0 = v 0 cos
- Equation 8: x(t)=v0cos(θ)t x ( t ) = v 0 cos
How do you find launch acceleration?
There is no horizontal force present for a vertical launch. The acceleration of the rocket can be determined by Newton’s Second Law of Motion. For a constant mass, this law can be written as force (F) equals mass (m) times acceleration (a); (F = m * a). We can solve for the acceleration using algebra ( a = F / m).
What is the formula for range in projectile motion?
Maximum Range of Projectile Now that the range of projectile is given by R = u 2 sin 2 θ g , when would be maximum for a given initial velocity . Well, since is a constant, for a given , depends on and maximum value of is . So, R m a x = u 2 g and it is the case when θ = 45 ∘ because at θ = 45 ∘ , 2 θ = 1 .
What is the horizontal distance traveled by a projectile?
range
The horizontal distance travelled by a projectile is called its range.
What is the acceleration of a catapult?
Catapult Physics. Acceleration, by definition, is the rate at which velocity or speed changes. For example, gravity caused the marshmellow to accelerate downward, at 9.8 m/s ², meaning that for every second it traveled, it’s speed increased by 9.8 m/s. The marshmellow’s vector affected its acceleration as well.
How do scientists predict the trajectory of a catapult?
Part of the scientific process involves figuring out what those factors are so you can make better predictions next time. Predicting the trajectory of a ball launched from the catapult requires an understanding of two fundamental physics concepts: projectile motion and conservation of energy.
How do I set the launch angle of the catapult?
A: The launch angle is set by inserting a metal pin through holes on the aluminum disk that align with the black metal base of the catapult. This picture shows the process: Q: How do I attach the rubber bands to the catapult?
What kind of energy is in a catapult?
In our case, we are dealing with kinetic energy (the energy an object with mass has according to its velocity) and potential energy (the energy that is stored in the rubber bands of the catapult). Note: We are ignoring a small amount of gravitational potential energy for now. All types of energy are usually expressed in units of joules (or J).
