Constructed Response: Work and answer will be scored on a 3 point rubric. Please answer in the space provided. After conducting a few experiments, the rover completes its journey by exiting the crater at a different location from where it entered. The rover travels up and out of the crater at a
steady upward Incline.
The path the rover travels out of the crater is a distance of 180 meters and covers a vertical distance of 65 meters.

Aspacecraft can attain a stable orbit 300 kilometers above earth if it reaches a velocity of 7.7 kilometers per second. the formula for a rocket's maximum velocity v in kilometers per second is vequalsminus0.0098tplusc ln upper r, where t is the firing time in seconds, c is the velocity of the exhaust in kilometers per second, and r is the ratio of the mass of the rocket filled with fuel to the mass of the rocket without fuel. find the velocity of a spacecraft whose booster rocket has a mass ratio of 20, an exhaust velocity of 2.1 km/s, and a firing time of 15 s. can the spacecraft achieve a stable orbit 300 km above earth?
