A cord can withstand 3,000 N of tension before it snaps. If a moving company uses this chord to hoist a 200 kg piano with an acceleration of 5.00 m/s2, will the
cord snap? *
a. No, the cord will not snap because there is 1,000N of force from the piano
b. Yes, the cord will snap because there is 5,000N of force from the piano
c. Yes, the cord will snap because there is 10,000N of force from the piano
d. No, the cord will not snap because there is 500N of force from the piano

You are sitting on the beach and wondering about the properties of mechanical waves. describe them in terms of ocean waves.

Adiver in midair has an angular velocity of 6.0 rad/s and a moment of inertia of 1.2 kg·m2. he then pulls is arms and legs into a tuck position and his angular velocity increases to 12 rad/s. the net external torque acting on the diver is zero. what is his moment of inertia in the tuck position?

Very large accelerations can injure the body, especially if they last for a considerable length of time. one model used to gauge the likelihood of injury is the severity index ( ), defined as =/ . in the expression, is the duration of the accleration, but is not equal to the acceleration. rather, is a dimensionless constant that = the number of multiples of that the acceleration is equal to.in one set of studies of rear-end collisions, a person's velocity increases by 13.7 km/h with an acceleration of 36.0 m/s2 . let the + direction point in the direction the car is traveling. what is the severity index for the collision?
