A spring gun is shot horizontally from a desk. The projectile leaves the gun at a...
THE EXPERIMENT The speed "." of a ball as it leaves the spring gun will be measured by projecting the ball horizontally (0-0) from a table top at a distance H above the floor. The gun is then elevated at a known angle 8. The position of the target is calculated using the measured value of v. calculated time of flight, and the equations of motion. A successful prediction with the projectile hitting the target means that the following concepts...
A spring-powered dart gun is un-stretched and has a spring constant 150 N/m. The spring is compressed by 8.00 cm and a 5.00 gram projectile is placed in the gun. The maximum height of the projectile when it is shot at an angle of 30.0 degrees above the horizontal from the gun is...?
The massless spring of a spring gun has a force constant k = 0.04 N/cm. When the gun is aimed vertically, a 19 g projectile is shot to a height of 5.0 m above the end of the expanded spring. (See below.) How much was the spring compressed initially? (Find d, in meters.)
A 60-g bullet is shot at a height of 200 m above ground, leaving the gun nozzle with a total kinetic energy of 240 N. What is its initial speed when it leaves the gun nozzle?
Q6 A projectile is fired horizontally from a gun that is 45.0 m above flat ground, emerging from the gun with a speed of 250 m/s. (a) How long does the projectile remain in the air? (b) At what horizontal distance from the firing point does it strike the ground? [3+2]
A projectile is fired horizontally from a gun that is 32.0 m above flat ground, emerging from the gun with a speed of 300 m/s. (a) How long does the projectile remain in the air? (b) At what horizontal distance from the firing point does it strike the ground? (c) What is the magnitude of the vertical component of its velocity as it strikes the ground?
A projectile is fired horizontally from a gun that is 66.0 m above flat ground, emerging from the gun with a speed of 250 m/s. (a) How long does the projectile remain in the air? (b) At what horizontal distance from the firing point does it strike the ground? m (c) What is the magnitude of the vertical component of its velocity as it strikes the ground? m/s
A 28 g ball is shot from a spring gun whose spring has a force constant of 367 N/m. The spring can be compressed 3 cm. How high will the ball go if the gun is aimed vertically? The acceleration of gravity is 9.81 m/s 2 . Assume that at the end of the barrel, the spring’s displacement and the ball’s height are each zero. Answer in units of m.
A toy gun uses a spring to project a 5.5-g soft rubber sphere horizontally. The spring constant is 8.0 N/m, the barrel of the gun is 14 cm long, and a constant frictional force of 0.033 N exists between barrel and projectile. With what speed does the projectile leave the barrel if the spring was compressed 6.0 cm for this launch? (Assume the projectile is in contact with the barrel for the full 14 cm.) _____m/s
A toy gun uses a spring to project a 4.6-g soft rubber sphere horizontally. The spring constant is 8.0 N/m, the barrel of the gun is 14 cm long, and a constant frictional force of 0.031 N exists between barrel and projectile. With what speed does the projectile leave the barrel if the spring was compressed 6.5 cm for this launch? (Assume the projectile is in contact with the barrel for the full 14 cm.) m/s
