Question

An astronaut using a jetpack (combined mass 80 kg) conducts a spacewalk on a trajectory far above the moon’s surface, moving 20 m/s at a 60° angle with the horizontal. A short burst of compressed nitrogen is ejected horizontally at 100 m/s (all velocities are relative to the moon’s surface). After this maneuver, the astronaut is moving vertically upward.

(a) What mass of gas was ejected?

(b) What are the astronaut’s new mass and speed?

You are abducted by aliens and find yourself locked in a large room on some strangeplanet. To pass the time, you decide to do some experiments using a ball-and-chain thatyou find on the floor. You make the following estimates:mBALL approximately equals 7 kg, mCHAIN approximately equals 0.5 kg, and CHAIN approximately equals 2 m. (a) When you hold the free end of the chain above your head and allow the ball to swinglike a pendulum, you use your wristwatch to measure the period as T approximately equals 4s. What is theacceleration due to gravity on this planet? Give explanation to your answer (b)If the ball accidentally hits a wall, how long does it take for this jolt in the chain totravel up to your hand?
A spaceship's orbital maneuver requires a speed increase of 1.05 ✕ 103 m/s. If its engine has an exhaust speed of 2.45 ✕ 103 m/s, determine the required ratio Mi Mf of its initial mass to its final mass. (The difference Mi − Mf equals the mass of the ejected fuel.)
Squids rely on jet propulsion when a rapid escape is necessary, providedthey have filled their mantle with water prior to escape. An empty 1.5kg squid initially drifting at 1.6m/s pulls in 0.10kg of water in its mantle, then ejects this water at a remarkable 45m/s. How fast is this squid moving right after filling up with water?
