What is the maximum height of a projectile?
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 reaches a maximum height of 233 m (neglecting air resistance).
How do you find the maximum range of a projectile?
If a projectile is launched at a speed u from a height H above the horizontal axis, and air resistance is ignored, the maximum range of the projectile is Rmax=ug√u2+2gH, where g is the acceleration due to gravity.
At what angle do you find the maximum range in projectile motion?
45 degrees
What are the three types of projectiles?
Three types of projectiles— the bullet, the round ball, and shot—are used in muzzleloaders.
How are projectiles used in real life?
In real life, the projectile motion finds applications in sports. Playing basketball, football is examples of projectile motion in real life. While throwing a basketball into the basket, the player shoots the ball in such a way that the flight taken by the ball is in the form of a parabola.
What are the 2 types of projectile motion?
In a Projectile Motion, there are two simultaneous independent rectilinear motions:
- Along the x-axis: uniform velocity, responsible for the horizontal (forward) motion of the particle.
- Along y-axis: uniform acceleration, responsible for the vertical (downwards) motion of the particle.
What is the initial velocity of an object being dropped at certain height?
Whether explicitly stated or not, the value of the acceleration in the kinematic equations is -9.8 m/s/s for any freely falling object. If an object is merely dropped (as opposed to being thrown) from an elevated height, then the initial velocity of the object is 0 m/s.
What is horizontal and vertical component of a vector?
The bottom edge of the triangle is the horizontal component and the side opposite the angle is the vertical component. The angle that the vector makes with the horizontal can be used to calculate the length of the two components.
What are horizontal and vertical components?
The horizontal velocity component (vx) describes the influence of the velocity in displacing the projectile horizontally. The vertical velocity component (vy) describes the influence of the velocity in displacing the projectile vertically.
What is the horizontal acceleration of a ball that is launched?
The horizontal velocity of a projectile is constant (a never changing in value), There is a vertical acceleration caused by gravity; its value is 9.8 m/s/s, down, The vertical velocity of a projectile changes by 9.8 m/s each second, The horizontal motion of a projectile is independent of its vertical motion.
How is the acceleration of falling objects affected by gravity?
When objects fall to the ground, gravity causes them to accelerate. Gravity causes an object to fall toward the ground at a faster and faster velocity the longer the object falls. In fact, its velocity increases by 9.8 m/s2, so by 1 second after an object starts falling, its velocity is 9.8 m/s.
Does the object change how fast it is moving in the horizontal direction?
An object’s horizontal position, velocity, or acceleration does not affect its vertical position, velocity, or acceleration. These motions can only be related by the time variable t. It is easy to forget that horizontal motion has constant velocity (and zero acceleration!)
