A ball with a mass of 1.5 kilograms is tied to the end of a rope. The ball is pulled to a height of 0.5 meters above the ground
and released. The ball has .....
joules of potential energy at position B. At position A, is ...... all of the energy changes to kinetic energy. The velocity of the ball at position A is
meters/second. Assume there’s no air resistance. Use g = 9.8 m/s2 , PE = m × g × h, and .
When petting a dog, mechanoreceptors in the skin of your hand send signals to the sensory neuron. The sensory neuron connects to your spinal cord and through your brain.
