Projectile motion with a few variables

In summary, the conversation discusses the calculation of acceleration for a projectile released at an angle of 60 degrees above the horizontal, with a launch position of 1m above the ground and a distance of 60m from the launch position. The equations for projectile motion are used, and the angle of 60 degrees is utilized to simplify the equations. The individual asking for help is able to solve the problem with the assistance of the expert.

Homework Statement

Assume uniform acceleration. The projectile is released at a height 1m above the ground traveling at angle 60 above the horizontal. It hits the ground 60m away from the launch position. Calculate acceleration of the particle in acceleration phase.[/B]

Homework Equations


s=ut+1/2ut^2 in y direction
s=ut in x direction[/B]

The Attempt at a Solution


tried using the above two and substituting for time and initial velocity but both give horrible equations which i can't solve.
Tried the range formula but that doesn't work because of the 2m start position.[/B]

The simple equal height for launch and landing range formula is out, so you need to fall back on the basic projectile motion equations. Fortunately the angle provided has well known values for sine and cosine, so writing the projectile motion equations in terms of an unknown velocity v is made a bit easier.

Why don't you show us your attempt using the projectile motion equations and point out where you get stuck?

Got it now. I was just being silly thank you for your help :)
 

Related to Projectile motion with a few variables

1. What is projectile motion?

Projectile motion is the motion of an object through the air that is affected by gravity. It follows a curved path called a parabola.

2. What are the variables involved in projectile motion?

The variables involved in projectile motion are initial velocity, angle of launch, time, acceleration due to gravity, and displacement.

3. How is the angle of launch related to the range of a projectile?

The angle of launch is directly related to the range of a projectile. The higher the angle of launch, the longer the range. However, if the angle is too high, the projectile will not travel as far due to air resistance.

4. How does air resistance affect projectile motion?

Air resistance can affect projectile motion by slowing down the object and altering its trajectory. It is more significant for objects with larger surface areas and slower velocities.

5. Can projectile motion be calculated for objects in real-life scenarios?

Yes, projectile motion can be calculated for objects in real-life scenarios by using the equations of motion and taking into account any external factors such as air resistance. However, these calculations may not always be accurate due to the complexity of real-world situations.
