What is the maximum height a projectile can reach?
Note also that the maximum height depends only on the vertical component of the initial velocity, so that any projectile with a 67.6 m/s initial vertical component of velocity will reach a maximum height of 233 m (neglecting air resistance).
What is the best way to analyze projectile motion?
The key to analyzing two-dimensional projectile motion is to break it into two motions, one along the horizontal axis and the other along the vertical. (This choice of axes is the most sensible, because acceleration due to gravity is vertical—thus, there will be no acceleration along the horizontal axis when air resistance is negligible.)
What happens to the vertical velocity as an object rises?
(c) The velocity in the vertical direction begins to decrease as the object rises; at its highest point, the vertical velocity is zero. As the object falls towards the Earth again, the vertical velocity increases again in magnitude but points in the opposite direction to the initial vertical velocity.
What is kinematics in two dimensional projectile motion?
This fact was discussed in Chapter 3.1 Kinematics in Two Dimensions: An Introduction, where vertical and horizontal motions were seen to be independent. The key to analyzing two-dimensional projectile motion is to break it into two motions, one along the horizontal axis and the other along the vertical.
What is the height of stage above the horizontal floor?
The flower is thrown from 2. 0 m above the horizontal floor with initial velocity. which is making an angle 3 7 ∘ above the horizontal. The height of stage above the horizontal floor is (g = 10 m s − 2)
Why is the initial velocity of an object in space positive?
Note that because up is positive, the initial velocity is positive, as is the maximum height, but the acceleration due to gravity is negative.
