Question A. How does the decrease in gravitational potential energy of a falling ball compare to its increase in kinetic energy?
Question B. What happens to the total of the gravitational potential energy plus the kinetic energy as a ball falls?Data:
Question C. What happens to the gravitational potential energy (Energy #1) as the ball falls?Question D. What happens to the kinetic energy (Energy #2) as the ball falls?Question E. What is one reason that some of the energy is ‘lost’ as the ball falls?Question F. What does the “Total Energy – Time” graph tell you about the total energy of the ball as it falls?
What is x and y coordinates of the shell
The wheel of the car has a radius of 0.340 m. The engine of the car applies a torque of 282 N•m to this wheel, that does not slip against the road surface. Since the wheel does not slip, the road must be applying the force of static friction to the w..
An unmarked police car, travelling a constant 94 km/h, is passed by the speeder travelling 153 km/h. precisely 0.70 s after the speeder passes, policeman steps on the accelerator. If the police car's acceleration is 2.30 m/s^2, how much time elapses ..
Assume air resistance is negligible; from what height (in cm) above the compressed spring was the block dropped.
Follow that with some of her work on repressed memories. After completing your readings on the WebLink, the textbook, and the PowerPoint presentation, address the prompts for your assignment.
What is an index of refraction of the liquid
A block of weight W can slide on a horizontal surface. A force of W/n1 is applied to the right that causes the block to accelerate with acceleration equal to g/n2. g is the acceleration by reason of gravity. If the coefficient of kinetic friction is ..
A radio station broadcasts at a frequency of 600,000 Hz. Know that radio waves have a speed of 3.00 x 10^8m/s, what is wavelength of these waves.
When G was first measured by Henry Cavendish, newspapers of the time hailed his experiment as "weighing Earth experiment." And Why.
An object with a net charge of 44 µC is placed in a uniform electric ?eld of 554 N/C, directed vertically. The acceleration of gravity is 9.81 m/s^2. What is the mass of this object if it ?oats in this electric ?eld?
A ranger in a national park is driving at 59 km/h while a deer jumps onto the road 61 m ahead of the vehicle. After a reaction time of t s, ranger applies the brakes to produce an acceleration of -3 m/s2. What is the maximum reaction time allowed if ..
