A dart gun includes a spring of spring constant k = 18 N/m which is used to shoot a dart of mass m. The dart leaves the gun at a speed of v = 4.1 m/s after the spring is compressed 1 cm. What is the weight, Fg in Newtons, of the dart? Part (b) What is the dart’s speed when it hits the floor vf, in m/s, if it is fired horizontally at a height of h = 2 meters? Part (c) What angle, θ in degrees, does the dart's final velocity make with the horizontal? Part (c) What angle, θ in degrees, does the dart's final velocity make with the horizontal? Part (c) What angle, θ in degrees, does the dart's final velocity make with the horizontal? Part (c) What angle, θ in degrees, does the dart's final velocity make with the horizontal? Part (c) What angle, θ in degrees, does the dart's final velocity make with the horizontal?

    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 toy dart gun contains a spring with a spring constant of 250 N/m. A 0.059 kg dart is pressed 0.05 m into the gun. a) If the gun is aimed directly upward, how high into the air will the dart travel when shot (measured from the compressed position in the gun)? b) What is the maximum velocity of the dart? c) If the dart got stuck to the spring: i) with what angular frequency will the dart oscillate (neglect...

    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...

    The spring of a spring gun has force constant k = 400 N/m and negligible mass. The spring is compressed 6.00 cm and a ball with mass 0.0300 kg is placed in the horizontal barrel against the compressed spring. The spring is then released, and the ball is propelled out the barrel of the gun. The barrel is 6.00 cmlong, so the ball leaves the barrel at the same point that it loses contact with the spring. The gun is...
