Virtual Lab: Ballistic Pendulum Introduction The ballistic pendulum was invented by Benjamin Robins in 1742 as a device mainly designed to accurately measure the speed of fast traveling projectiles (bullets or cannon balls), relying only on measurements of mass and distance, without measurements of time. Knowing the mass of the projectile, estimates of its momentum and kinetic energy could also be made. Although the ballistic- pendulum method has lost its practical importance to more modern methodologies, it was used for...
A projectile of mass m is shot into a block of mass M. The block is initially at rest at the edge of a frictionless table. The table top is a height h above the floor. The projectile hits and sticks to the block. After impact the masses land a distance d from the edge of the table. Determine the expression for the initial speed of the projectile.
3. Given the initial firing angle 9 of a projectile, find the launch speed V , such that the projectile just hits the other side of the ravine a horizontal distance away of D
3. The ballistic pendulum is a device used to measure the speed of a projectile, such as a bullet. The projectile, of mass m, is fired into a large block of mass M, which is suspended like a pendulum. As a result of the collision, the pendulum and projectile together swing up to a maximum height h. Determine the relationship between the initial horizontal speed of the projectile, v, and the maximum heighth
A bullet of mass 45 g hits a block of mass 3.66 kg with a speed v. After the collision, the bullet emerges at the other end of the block with a speed of 87 m/s, and the pendulum swings up over an angle of 38°. If the string of the pendulum is 3.6 m, what was the initial speed v of the bullet? st
A projectile is fired with an initial speed of 150 m/s and angle of elevation π/3. The projectile is fired from a position 110 m above the ground. ( Recall g = 9.8m/s^2). Find the time the projectile hit the ground. Find the range of the projectile. show your work please!!
A projectile is launched from ground level with an initial speed of 43.5 m/s at an angle of 31.9° above the horizontal. It strikes a target in the air 1.73 s later. What is the horizontal distance from where the projectile was launched to where it hits the target? horizontal : m What is the vertical distance from where the projectile was launched to where it hits the target? vertical : m
A projectile is launched at an angle 10º below horizontal with initial speed 70 m/s from the edge of a vertical cliff. In a while the projectile hits the ground with speed 120 m/s. Find horizontal distance traveled by the projectile, total displacement and height of the cliff.
A projectile is launched with an initial speed of 20 m/s horizontally from a point 100 m above the ground. What angle does the velocity make with the horizontal when the projectile hits the ground?
A projectile is launched from ground level with an initial speed of 45.5 m/s at an angle of 32.5° above the horizontal. It strikes a target in the air 2.64 s later. What is the horizontal distance from where the projectile was launched to where it hits the target? horizontal: 59.59 What is the vertical distance from where the projectile was launched to where it hits the target? Im vertical: 74.19
