A person on a stationary skateboard throws a bowling ball with a velocity of 5.0 m/s. What is a possible speed of the person after the throw? 7.8 m/s

5 m/s

0 m/s

2 m/s

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

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

The upward force acting on the wing of a airplane in flight is known as the "lift" force. (d)
