An 50 kg student runs and jumps onto a 25 kg tire swing, which is initially at rest, and rides the swing up into the air. The swing (and the student) then rises a vertical distance of 1.5 m. What was the initial speed, in m/s, of the swing? Remember the acceleration due to gravity near Earth's surface, g = 9.81 m/s A. 29 m/s

B. 5.4 m/s

C. 1.7 m/s

D. 15 m/s

E. 3.8 m/s

Please help its for my final

answer: i'm not sure which is which for i get confused on it all the time but i can tell you that the answer lies with the convex and concave devices. i hope this you. have a good day and best of luck to you!

explanation:

another example of kinetic energy would be,

kinetic energy   >     moving energy

answer   >   letter choice (c),   a hammer falling off a table.

hope that !                                         : )
