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?

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.

Which of the following statements is most closely associated with Einstein's general theory of relativity?
Fudgin [204]
The answer is the first one. That's because the general theory of relativity is the thing experiencing whatever is experiencing relative to something else. The second answer is just plain wrong. The third answer is just a constant, and doesn't relate to experiencing anything. And the fourth answer is a force between two objects, and it has no second comparison. The first answer is how a subject experiences two different things.

Annie has a soccer ball and a kickball. She kicks each ball with the same force. The soccer ball accelerates at 3 m/s2, and the
klasskru [66]

Answer:

a= F/m

Explanation:

Newton's Second Law of Motion : It states that that the rate of change of momentum of a body is proportional to the applied force and it takes place on the direction of the force applied.

Mathematically,

F = m ( v-u)/t

F = ma

a = F/m

The same force was applied to each of the balls yet, the acceleration of one was greater than the other. The kickball accelerated at a greater pace than the soccer ball because it has a lesser mass hence the effect or impact of the force applied will be greatly felt by the kickball.
