A child fires a foam dart from a dart gun. The dart initially travels with a speed of 6.00 m/s horizontal to the ground. The dart strikes the ground at a horizontal distance of 2.00 m from where the dart was fired. How high above the ground was the dart when it was fired?
The dart undergoes a projectile motion with an initial velocity of 6m/s only in the x direction.
Therefore here, we use the 2nd equation of motion to-
1) Calculate the time of travel in the x direction
2) Calculate the height in y direction using the time of travel

A dart gun is fired while being held horizontally at a height of 1.00 m above ground level and while it is at rest relative to the ground. The dart from the gun travels a horizontal distance of 5.00 m. A college student holds the same gun in a horizontal position while sliding down a 45.0° incline at a constant speed of 2.00 m/s. How far will the dart travel if the student fires the gun when it is 1.00...
1. The potential energy stored in the compressed spring of a dart gun, with a spring constant of 48.00 N/m, is 0.940 J. Find by how much is the spring is compressed. 2. A 0.070 kg dart is fired straight up. Find the vertical distance the dart travels from its position when the spring is compressed to its highest position. 3. The same dart is now fired horizontally from a height of 1.10 m. The dart remains in contact until...
A dart gun consists of a spring (k = 367 N/m) and a 25.0 g dart. When the dart is loaded into the gun, the spring is compressed 7.0 cm. The gun is aimed straight up and fired. a) How high does the dart go, ignoring air resistance of course? b) How fast is the dart going when it comes back down to the horizontal level at which it was fired?
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 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?
U ed 20. Gun play. A toy dart gun launches a 111-gram rubber dart by releasing a compressed spring. If the spring constant is 239 N/m and the spring is compressed 6.00 cm before firing, how much elastic potential energy is stored in the spring? Use the work-energy theorem to calculate the the horizontal launch velocity of the dart. A second dart gun launches the same dart at 2.67 m/s when compressed 7.25 cm. What is the spring constant of...
A pellet gun is fired straight downward from the edge of a cliff that is 13.6 m above the ground. The pellet strikes the ground with a speed of 27.2 m/s. How far above the cliff edge would the pellet have gone had the gun been fired straight upward?
A pellet gun is fired straight downward from the edge of a cliff that is 13.5 m above the ground. The pellet strikes the ground with a speed of 28.1 m/s. How far above the cliff edge would the pellet have gone had the gun been fired straight upward?
A pellet gun is fired straight downward from the edge of a cliff that is 19.6 m above the ground. The pellet strikes the ground with a speed of 36.0 m/s. How far above the cliff edge would the pellet have gone had the gun been fired straight upward?
A cannon fires a cannonball at some angle with respect to the horizontal. It travels a horizontal distance of 26.9 meters and hits the ground in 2.5 seconds. Assume that it lands at the same level as at which it was fired and that there is no air drag. what is the initial speed at which the cannonball was fired?
