Khaled Mohamed Aldab Hareb Alshamsi 2/4, 10:46 AM 6.51 A slingshot that launches a stone horizontally consists of two light, identical springs (with spring constants of 30.0 N/m) and a light cup that holds a 1.00 kg stone. Each spring has an equilibrium length of 50.0 cm. When the springs are in equilibrium, they line up vertically. Suppose that the cup containing the mass is pulled to x = 70.0 cm to the left of the vertical and then released. Determine a) the system's total mechanical energy; b) the speed of the stone at x = 0. = 0.7 m www. 0.5 m -*- 0.5 m

- How do you measure the mass of an astronaut in orbit? (You can't just use a scale!) For the 1973 - 1979 Skylab program (Skylab was a space station that predated the current International Space Station), NASA engineers designed a Body Mass Measuring Device (BMMD). This is essentially a chair of mass m mounted on a spring with a carefully measured spring constant ks = 605.6 N/m. (The other end of the spring is connected to the Skylab itself, which has a mass much larger than the astronaut or the chair, and so remains essentially fixed as the astronaut oscillates.) The period of oscillation of the empty chair is measured to be 0.90149 s. When an astronaut is sitting in the chair, the period is 2.12151 s. What is the astronaut's mass? Please describe your reasoning!A spring with spring constant k=600 N/m is compressed by 10 cm and launches a ball vertically into the air. The mass of the ball is 2.0 kg. Determine how high the ball will be launched.A 205 g object is attached to a spring that has a force constant of 76.5 N/m. The object is pulled 7.25 cm to the right of equilibrium and released from rest to slide on a horizontal, frictionless table. Calculate the maximum speed vmax of the object. Umax = m/s Find the locations of the object when its velocity is one-third of the maximum speed. Treat the equilibrium position as zero, positions to the right as positive, and positions to the left as negative. position: cm position: cm
- A box is motionless, sitting on a ramp with an incline of 0 =54.4 ° being pulled in the direction up the ramp by a spring with a spring constant of k=150 N/m that is stretched x=6.4 m. The coefficient of friction between the ramp and the box are u s=0.53 and u k=0.15 and the friction force is going down the ramp. What is the mass of the box? Solve symbolically: Solve numerically: m= Units: If the box starts moving up a ramp with an acceleration of a=2.41 m/s, what is the new length that the spring will stretch? Solve symbolically: Solve numerically: Units:Question in pic.In starting a game of pinball, the 44.7 g ball rests on a spring, of spring constant k = 18.8 N/m, that has been compressed by 0.0900 m. If the spring is released, how far up the pinball table (which is inclined at 39.0°) does the ball go before rolling back down again? You can assume it doesn't hit any obstacles on the way up.

Block A has a mass of 2kg and block B has a mass of 10 kg. The spring shown is unstretched when block B is in contact with the ground. The system is released from rest in the position shown.
