what does u and is stand for?mtayab1994 said:No remember that since the object is traveling up it will have a negative speed therefore:
Vf^2=u^2+2is
I am solving for Vf^2 which is vertical speed final?mtayab1994 said:0=(initial speed)^2-2(speed of gravity)s than once you have this down just solve the equation.
Your second equation looks promising. In more compact terms:Casey314stl said:Homework Statement

The ball's maximum height is determined by its initial velocity, the angle at which it is thrown, and the force of gravity.
The maximum height of a ball can be calculated using the equation: h = (v^2 * sin^2(theta)) / 2g, where h is the maximum height, v is the initial velocity, theta is the angle at which it is thrown, and g is the acceleration due to gravity (9.8 m/s^2).
Yes, air resistance can affect the ball's maximum height. Depending on the shape and speed of the ball, it can either increase or decrease the maximum height.
The mass of the ball does not affect its maximum height, as long as the initial velocity and angle remain constant. However, a heavier ball may lose more energy to air resistance and therefore have a slightly lower maximum height compared to a lighter ball.
Yes, the ball's maximum height will change on different planets because the force of gravity varies on each planet. The maximum height can be calculated using the same equation, but with the corresponding value for acceleration due to gravity on that planet.
