A child is on a pogo stick. At the top of her jump, kinetic energy (KE) = 0 J, gravitational potential energy (GPE) = 100 J, and the potential energy in the spring (SPE) = 0 J. At which point in the jump is the kinetic energy the greatest?
1 answer:
Because just before the pogo stick contacts the ground the system has its greates velocity.
2.) A
Because they have the same mass and the same height.
3.) D
Because the velocity is 0 (KE is 0), The Height is 0 (GPE = 0) and the spring is compressed due to converting all the kinetic enrgy into SPE.

Answer:
Explanation:
Positive values for position indicate that the object is in front of the starting point and negative values tell us that the object is behind the starting point. (time = 9.5, position = 0) the object is at the starting point.
Answer:
B
Explanation:
in a liquid the particles are widespread and move around each other but in a solid they move in place and are tightly packed
