A 120-ton tugboat is moving at 6 ft/s with a slack towing cable attached to a 100-ton barge that is at rest. The cable is being unwound from a drum on the tugboat at a constant rate of 5.4 ft/s and that rate is maintained after the cable becomes taut. Neglecting the resistance of the water, determine (a) the velocity of the tugboat after the cable becomes taut, (b) the impulse exerted on the barge as the cable becomes taut.

- A 16-Mg jet airplane maintains a constant speed of 774 km/h while climbing at an angle a = 18°. The airplane scoops in air at a rate of 300 kg/s and discharges it with a velocity of 665 m/s relative to the airplane. If the pilot changes to a horizontal flight while maintaining the same engine setting, determine (a) the initial acceleration of the plane, (b) the maximum horizontal speed that will be attained. Assume that the drag due to air friction is proportional to the square of the speed.arrow_forwardAn orbiting satellite has a mass of 5000 kg and is travelling at a constant velocity of V0. To alter its orbit, an attached rocket discharges 100 kg of gases from the reaction of solid fuel at a speed of 3000 m/s relative to the satellite in a direction opposite V0. The fuel discharge rate is constant for 2 s. Determine(a) The thrust exerted on the satellite.(b) The acceleration of the satellite during this 2 s period.(c) The change of velocity of the satellite during this time period.arrow_forwardA block with mass 0.400 kg is on a horizontal frictionless surface and is attached to a horizontal compressed spring that has force constant k=200N/m The other end of the spring is attached to a wall. The block is released, and it moves back and forth on the end of the spring. During this motion the block has speed 3.00 m/s when the spring is stretched 0.160 m. During the block's motion, what is the maximum distance the spring is compressed from its equilibrium position? When the spring has its maximum compression, what is the speed of the block and what is the magnitude of the acceleration of the block?arrow_forward
- A block with a mass of m is dropped from a certain height. An undeformed spring with a spring constant of 450 N/m is placed directly below it. The distance between the top of the spring and the block is 3 m. Determine the magnitude of velocity of the block just before it hits the spring (use principles of work and energy) and prove using kinematic equations Determine the deformation of the spring as the block reaches its lowest point. (use principles of work and energy) Determine the magnitude of the velocity of the block as the spring returns to its original length. use (principles of work and energy) hello please help thank youuuu very very urgentarrow_forwardA 4-kg collar is attached to a spring and slides without friction in a vertical plane along the curved rod ABC. The spring is unstretched (- ė jall el) when the collar is at C and its constant is 700 N/m.

He is loaded into a spring‑powered gun pointing up at some angle and is shot into the air. The gun's spring has a force constant of 54.7 N/m and is initially compressed a distance of 0.137 m from its relaxed position. If Mickey has a constant horizontal speed of 2.27 m/s while he is flying through the air, how high h above his initial location in the gun does Mickey soar? Assume g = 9.81 m/s^2.arrow_forward
- A launch vehicle has 6 engines operating in parallel which are fed from the same propellant tank. Initially, each engine has an equivalent exhaust velocity of 3500 m/s and consumes 400 kilograms of propellant per second. One of the engines malfunctions and consequently operates at 50% thrust and 120% propellant consumption. Calculate the equivalent exhaust velocity in m/s of all engines if treated as a single engine, including the malfunctioning engine in your calculation.arrow_forwardCollar A has a mass of 3 kg and is attached to a spring of constant 1200 N/m and of undeformed length equal to 0.5 m. The system is set in motion with r = 0.3 m, v0 = 2 m/s, and vr = 0. Neglecting the mass of the rod and the effect of friction, determine (a) the maximum distance between the origin and the collar, (b) the corresponding speed. (Hint: Solve the equation obtained for rby trial and error.)arrow_forwardA 32,000-lb airplane lands on an aircraft carrier and is caught by an arresting cable. The cable is inextensible and is paid out at A and b from mechanisms located below deck and consisting of pistons moving in long oil-filled cylinders. Knowing that the piston-cylinder system maintains a constant tension of 85 kips in the cable during the entire landing, determine the landing speed of the airplane if it travels a distance d= 95 ft after being caught by the cable.arrow_forward
