Asteamboat moves with velocity components of 6 km/hr along the x direction and 8 km/hr along the y direction. what is the direction of the steamboat with respect to the x axis?

Which simple machine is not part of this compound machine? a. lever b. pulley c. inclined plane d. wheel and axle

The 10-kg double wheel with radius of gyration of 125mm about o is connected to the spring of stiffness k = 600 n/m by a cord which is wrapped securely around the inner hub. if the wheel is released from rest on the incline with the spring stretched 225 mm, calculate the maximum velocity v of its center o during the ensuing motion. the wheel rolls without slipping

Suppose an objects initial velocity is 10m/s and it’s final velocity is 4 m/s. mass is constant. what can best be concluded about the object based in the work-energy theorem
