A string of linear mass density 4.9 × 10−3 kg/m is stretched by a 441 N tension force, and fixed at both ends. For a standing wave pattern oscillating at 150 Hz on the string, the smallest Node−Antinode

distance is:​

What is the momentum of a 2 kg object moving at 15 meters per second

Amass weighing 24 pounds, attached to the end of a spring, stretches it 4 inches. initially, the mass is released from rest from a point 8 inches below the equilibrium position. find the equation of motion. (use g = 32 ft/s2 for the acceleration due to gravity.)

Alarge cruise ship of mass 7.00 ✕ 107 kg has a speed of 11.6 m/s at some instant. (a) what is the ship's kinetic energy at this time? (b) how much work is required to stop it? (give the work done on the ship. include the sign of the value in your answer.) (c) what is the magnitude of the constant force required to stop it as it undergoes a displacement of 3.00 km?
