a flowerpot falls from a windowsill 25.0 m above the sidewalk. How fast is the flowerpot moving when it strikes the ground?
A flowerpot is knocked off a balcony 23.9 m above the sidewalk and falls toward an unsuspecting 1.93 m tall man who is standing below. How close to the side walk can the flower pot fall before it is too late for a warning shouted from the balcony to reach the man in time? Assume that the man below requires 0.138 s to respond to the warning, and the velocity of sound in air to be 341 m/s. The acceleration...
A flowerpot is knocked off a balcony 26.7 m above the sidewalk and falls toward an unsuspecting 1.76 m tall man who is standing below.

An 0.80-m conducting rod is dropped from rest from a bridge 25.0 m above the surface below. As it falls, it remains parallel to the ground and its length remains along the east-west direction. Just before the rod hits the ground below, the induced emf across its length is 6.5×10-4 V. Assuming the earth’s magnetic field at this location points due north. a) Determine the magnitude of the earth’s magnetic field at this location (just above the ground). b) Which...
