Answer:
KE=800,000
Explanation:
The formula for kinetic energy is KE=1/2mv^2 or Kinetic Energy= 0.5*mass*velocity^2
so 1000 is the mass and 40 is the velocity
KE=0.5*1000*40^2
KE=0.5*1,000*1,600
KE=800,000 Joules
i just took the test on edg enuity it was B.The mass of the rocket decreases as fuel is burned, so the acceleration increases.
12.5 times 14 and convert to meters its 1.75 meters per second
