A spring-loaded dart gun is used to shoot a dart straight up into the air, and the dart reaches a maximum height of 19,79 meters above its point of release. The same dart is shot up a second time from the same gun, but this time the spring is compressed only half as far (compared to the first shot). How far up does the dart go this time? (Neglect friction and assume the spring is ideal and massless.) Answer in...

A ball of mass 0.083 kg is shot straight up in the air using a compressed spring. The spring has a spring constant of 328 N/m and is compressed by 0.05 m initially. The ball reaches a height of 0.252 m above the initial position. How much energy has dissipated due to frictional effects such as air drag ? (in J)

A spring-loaded toy gun is used to shoot a ball of mass m=1.50kg straight up in the air, as shown in (Figure 1) . The spring has spring constant k=667N/m. If the spring is compressed a distance of 23.0 cm 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 gun. Assume that...
A 28 g ball is shot from a spring gun whose spring has a force constant...
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.

The firing mechanism of a toy rifle is made up of a
spring whose constant is unknown. When the spring compresses 0.12m,
the rifle, if fired vertically, is capable of launching a 35g
projectile up to a maximum height of 20m above the position of the
projectile prior to firing. Ignore the friction forces and
determine the spring constant.
How fast is the projectile at point B?

9. A spring-loaded toy gun is used to shoot a ball of mass m-2.50 kg straight up in the air, as shown below. The spring has spring constant k-500 NI/m. If the spring is compressed a distance of 20.0 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 gun. Assume that...
