Suppose the skater is at the highest point in the jump. What are the relative amounts of the skater’s kinetic and gravitational potential energy at that point? A. all kinetic energy, no gravitational potential energy
B. half kinetic energy, half gravitational potential energy
C. no kinetic energy, all gravitational potential energy
D. no kinetic energy, no gravitational potential energy

3.Which of the following statements about the kinetic and potential energy of the skater are true? You may select more than one answer.
A. As the skater rolls up the side of the half-pipe, the skater gains kinetic energy.
B. The skater has no gravitational potential energy at the bottom of the half-pipe.
C. Gravitational potential energy becomes kinetic energy when the skater rolls down the side of the half-pipe.
D. The skater transfers gravitational potential energy to the skateboard.

7 + 6

5 + 11

Step-by-step explanation:

the lengths of the two shorter sides of a triangle must add up to more than the length of the third side.

3 + 4 = 7 ≤ 8    no

7 + 6 = 13 > 12   yes

5 + 11 = 16 > 13  yes

4 + 6 = 10 ≤ 12  no

4 + 6 = 10 ≤ 10  no
