The spring oscillates to the other end. The amplitude is 3.5m, k = 1.2, and angular frequency is = 4.3 . Solve the wave speed.
Block 1 of mass m1 = 2 kg is placed on block 2 of mass m2 = 3 kg which is then placed on a table. A string connecting block 2 to a hanging mass M passes over a pulley attached to one end of the table, as shown in Fig. 1. The mass and friction of the pulley are negligible. The coefficients of friction between block 1 and block 2 are μ1s = 0.2, μ1k = 0.1 and between block 2 and the tabletop air μ2s = 0.3, μ2k = 0.15. Draw the complete free body diagram of the system and determine the largest value of M for which the blocks can remain at rest.
At the same rotational speed and coefficient of static friction between sock and the drum, would a sock of twice the mass slide down the wall? Explain your answer
A long distance swimmer is able to swim in calm water at 4.0 km / h. She wants to try swimming from Port Angeles, Washington, directly north to Victoria, British Columbia, a distance of 50 km. An ocean current crosses the Strait of Juan de Fuca from west to east at 3.0 km / h. In what direction (relative to North) must you swim to cross a straight line between the two cities?An aircraft heads north at 320km/h relative to the wind . The wind velocity is 80km/h from the north. Find the velocity of the aircraft relative to the aircraft relative to the ground
What is the density of water when:
The weight of an empty cylinder was 50 g, 20 mL of water was placed in the graduated cylinder, and the weight of the cylinder and water was 70 g.
