Ana kicks a stationary 0.2 kg soccer ball. The ball leaves her foot at a speed of 20 m/s. a. What impulse was delivered to the ball?
b. The ball experiences 40N of force during the kick. How long were the ball and
foot in contact?

Is it possible to use the energy from two atoms colliding to create a clean burning lasting fuel source with a large amount of force? is it also possible to harness that energy from the two atoms colliding to create a clean energy source that will last for years from just two atoms colliding. is there a possibility to control and store that energy for years but slowly let the energy out enough to power cities cheaper and faster.

Work out sian speed for the first 30 minutes of her journey. give your answer in km/h.
