4 dni temu · The equation for the distance traveled by a projectile being affected by gravity is sin (2θ)v2/g, where θ is the angle, v is the initial velocity and g is acceleration due to gravity. Assuming that v 2 /g is constant, the greatest distance will be when sin (2θ) is at its maximum, which is when 2θ = 90 degrees.

The time for projectile motion is completely determined by the vertical motion. So any projectile that has an initial vertical velocity of 14.3 m / s 14.3 m / s and lands 20.0 m below its starting altitude will spend 3.96 s in the air.
There is no vertical component in the initial velocity (\(\mathrm{v_0}\)) because the object is launched horizontally. Since the object travels distance \(\mathrm{H}\) in the vertical direction before it hits the ground, we can use the kinematic equation for the vertical motion: \[\mathrm{(y−y_0)=−H=0⋅T−\dfrac{1}{2}gT^2}\]
The velocity that is given has both x and y components, because it is in a direction 60.0° up from the horizontal (x) direction. The initial velocity can be broken down using an equation relating the sine and cosine: 1 = cos 2 θ + sin 2 θ. We multiply both sides by the initial velocity squared v o 2: (v o 2)(1) = (v o 2)(cos 2 θ) + (v o 2 ...
The time for projectile motion is determined completely by the vertical motion. Thus, any projectile that has an initial vertical velocity of 21.2 m/s and lands 10.0 m above its starting altitude spends 3.79 s in the air. (b) We can find the final horizontal and vertical velocities v x v x and v y v y with the use of the result from (a).
11 sie 2021 · Thus, any projectile that has an initial vertical velocity of 21.2 m/s and lands 10.0 m above its starting altitude spends 3.79 s in the air. We can find the final horizontal and vertical velocities v x and v y with the use of the result from (a).
In the diagram, a particle is thrown with speed \ (u\) at an angle of \ (\theta\) with the horizontal. An analysis of the motion of the projectile starts by breaking the components of initial velocity and acceleration into horizontal (along \ (x\)-axis) and vertical (along \ (y\)-axis) components.
