A projectile launcher is loaded by providing an average force of 23 N to compress a spring 12 cm. If the projectile has a mass of 5.7 grams and is shot at an angle of 57 degrees at a height of 1.37 meters above the floor, what is the spring constant of the launcher, muzzle velocity of the ball, time in the air, maximum height and horizontal distance travelled?

    Engr 135 Program #6 Spring 2019 Cannon Muzzle Velocity& Projectile Impact Point Part I- Cannon Muzzle Velocity We wish to determine the muzzle velocity of a physics lab spring "cannon." The cannon will be fired from a table top, with the cannon itself parallel to the floor. It is established that the height of the bottom of the ball, just as it is leaving the cannon, is Yo in meters. We assume that for the short distances and velocities involved,...

    Part A A small spring-loaded launcher is designed to fire steel ball bearings with masses of 0.28 kg. When setting the launcher, you compress the spring a distance of 13 cm. You then fire the launcher straight up and find that the projectiles reach a maximum height of 1 m above the point that they leave the launcher. You load another ball bearing, compress the spring a distance of 19 cm, and place it horizontally at the edge of a...

    A projectile launcher as shown in the Figure is used to launch 0.5 kg ball into the air. The launcher is connected to a 1kg mass and starts from rest with the spring compressed to a length of 15 cm. The un-stretched length of the spring is 75 cm. When the launcher is released from rest, the 1kg mass will impact the ball and the ball wil project in the air. Determine a suitable spring constant and angle 8 for...

    We pitch a ball into the air, the ball follows (straight line/arc) path. Assuming that air resistance is negligible, what force is acting on a projectile during its flight? In what direction? The horizontal distance (range) a projectile travelled depends on the (launch angle/lunch speed/both) A ball is launched by a spring loaded launcher at an initial speed. We can measure the initial (launch) speed in the lab by: Launch the ball straight up and measure the maximum height it...

    A spring-loaded launcher is used to shoot a ball of mass 1.50 kg straight up in the air, as shown in (Figure 1). The spring has spring constant k 667 N/m. If the spring is compressed a distance of 25.0 centimeters from its equilibrium position y = 0 and then released, the ball reaches a maximum height hmax (measured from the equilibrium position of the spring). There is no air resistance, and the ball never touches the inside of the...
