This is an example of: A model rocket is launched and is descending.

Question 1 options:

A. potential energy

B. kinetic energy

C. both

C. both

Explanation:

kinetic energy bcs it's moving and gravitational potential energy for it's descend.

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this
