Elaine and her bike have a combined mass of 50 kg. in a bicycle race, elaine uses the pedals to create a forward force of 75 n. assume that there is a constant 15 n of air resistance and an additional 10 n of rolling friction from the wheels. what will happen when the air resistance force combined with the friction are equal to 75 n?

If jerome is swinging on a rope and transferring energy from gravitational potential energy to kinetic energy, is being done.

Suppose a soccer ball is kicked from the ground at an angle 20.0º above the horizontal at 8.00 m/s. the y-velocity is determined to be 2.74 m/s. how long will the ball be in the air? assume the ball lands at the same height at which it was kicked.

The bubbles in a carbonated soft drink are produced when carbonic acid decomposes to form carbon dioxide and water. in a closed system, this equilibrium exists as why does a carbonated soft drink lose carbonation when the container is left open? a. water evaporates, which favors the formation of h2co3. b. pressure decreases, which favors the formation of h2co3. c. the open container warms up, which causes more gas to escape. d. co2is removed, which favors the formation of h2co3.
