Homework Statement
A ball is launched at 30 degrees. How far away will it land if dy= 56.2m (height of launch)
Homework Equations
t=vy/g
The Attempt at a Solution
t=vy/9.8m/s
I can't figure out how to find either vy or t
Heck, I can't figure out what dy = 56.2 is supposed to be. Does it have units? Is it a velocity? A distance? What?lkadfj said:Homework Statement

You seem to be saying that dy is the height from which it was launched (compared with the landing point, presumably). But if so, there's not enough information. From the name 'dy' I would guess it might mean the maximum height reached (as in, delta y), and that the landing point is on the same level as the launch point. If so, there is enough information.lkadfj said:A ball is launched at 30 degrees. How far away will it land if dy= 56.2m (height of launch)
A projectile problem is a type of physics problem that involves calculating the motion of an object that is launched or thrown into the air. These problems typically involve finding the distance, height, and/or time of flight of the object.
To find the distance of a ball launched at 30 degrees, you can use the formula d = v2 * sin(2θ) / g, where d is the distance, v is the initial velocity of the ball, θ is the launch angle (in radians), and g is the acceleration due to gravity (9.8 m/s2). Plug in the values and solve for d.
The launch angle of 30 degrees is important because it is the angle at which the horizontal and vertical components of the initial velocity are equal. This means that the object will travel the furthest distance before hitting the ground, making it the optimal angle for maximum distance in a projectile problem.
No, the formula for distance in a projectile problem only works for a launch angle of 30 degrees. For other launch angles, you will need to use a different formula or adjust the values in the formula to account for the different angle.
Yes, projectile problems have many real-world applications, such as in sports like baseball and basketball, where players need to calculate the height and distance of their throws or shots. They are also used in engineering and design, such as in calculating the trajectory of a rocket or missile launch.
