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...
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 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...
A toy gun uses a spring with a force constant of 350 N/m to propel a 14.0 g steel ball. The spring is compressed 8.80 cm and friction is negligible. (a) How much force (in N) is needed to compress the spring? (Assume the gun is aimed in the positive direction. Indicate the direction with the sign of your answer.) (b) To what maximum height (in m) can the ball be shot? (c) At what angles above the horizontal (in...
A spring-loaded toy gun is used to shoot a ball of mass m=1.50 kg straight up in the air, as shown in (Figur 1) . The spring has spring constant k =667 N/m. If the spring is compressed distance of 25.0 centimeters from its equilbriurn position y = 0 and then released, the ball reaches a maximum height hax (measured from the equilibrium position of the spring). There is no air resistance, and the ball never touches the inside of...
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...
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...
1. 2. A spring-loaded toy gun is used to shoot a ball of mass M straight up in the air. The ball is not attached to the spring. The ball is pushed down onto the spring so that the spring is compressed a distance S below its unstretched point. After release, the ball reaches a maximum height 35, measured from the unstretched position of the spring (see diagram below). Maximum Height Spring unstretched Spring compressed Mass released from west will...
1. Bull's-Eye Bonanza. (Allotted Time 45 minutes) Suppose you want to throw a dart across a room at a wall-mounted target and hit the target exactly at its center point. We call this center point of the target its "bull's eye". The bull's-eye is a horizontal distance d from the dart's point of release and a height h above the dart's point of release. To hit the bul'seye, you have a choice of the speed s at which you throw...
