A 2.8 kg melon is launched straight upwards with an initial velocity of 34 m/s , ignoring air resistance, how high will the melon reach above the ground?

b. If the melon actually reaches a height of only 40 m, calculate the average
force of air resistance acting against the melon as it rises,

You will hear a hissing sound because of the carbon dioxide escaping the can or bottle

The rearrangement of particles in a physical change. hope this

W= fd
where f is an applied force and d is the distance over which it is applied. when a parachuting skydiver is at constant velocity, he is experiencing "terminal velocity", the point at which his acceleration down is canceled out by air resistance. that means that the resisting force of the air is equal to his weight, but in the opposite direction. with this, we can solve for the work done by the force.
w = fd
w = (92.0)(9.81 m/s^2) (325)
w= 2.93 x 10^5 j
the value for work in this case is positive because it is pushing up on the skydiver, who has a downward force of gravity.
therefore the answer is 2.93 x 10^5 j
