How does Newton's third law explain how a rocket is launched upward? A. The force of Earth's gravity balances with the force of the rocket engines. B. The mass of the rocket determines how much force is needed to move it into orbit. C. The rocket will remain motionless on the launchpad until an unbalanced force is applied. D. The force it exerts on its exhaust gases is equal to the force the exhaust gases exert on the rocket.

Compare the horizontal displacement of the two balls as they travel to the ground. what do you observe?

Aball is thrown from the top of a building with an initial velocity of 21.9 m/s straight upward, at an initial height of 51.6 m above the ground. the ball just misses the edge of the roof on its way down, as shown in the figure. (a) determine the time needed for the ball to reach its maximum height. (b) determine the maximum height. (c) determine the time needed for the ball to return to the height from which it was thrown, and the velocity of the ball at that instant. (d) determine the time needed for the ball to reach the ground. (e) determine the velocity and position of the ball at t = 5.35 s.

Row old is the rock laver2. if this sedimentary rock layer is truly the oldest one of marine origin, what do you think that tells usabout the formation of earth's oceans?
