A ball with a mass of 275 g is dropped from rest, hits the floor and rebounds upward. If the ball hits the floor with a speed of 3.50 m/s and rebounds with a speed of 1.50 m/s, determine the following. (a) Magnitude of the change in the ball's momentum in kg · m/s (Let up be in the positive direction.) (b) Change in the magnitude of the ball's momentum in kg · m/s (Let negative values indicate a decrease in magnitude.) (c) Which of the two quantities calculated in parts (a) and (b) is more directly related to the net force acting on the ball during its collision with the floor? 1. The magnitude of the change in the ball's momentum2. Neither are related to the net force acting on the ball. 3. They both are equally related to the net force acting on the ball.4. The change in the magnitude of the ball's momentum
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.)
The Merlin rocket engines developed by SpaceX can produce 7.12 ✕ 105 N of instantaneous thrust with an exhaust speed of 3.05 ✕ 103 m/s in vacuum. What mass of fuel does the engine burn each second to produce this thrust? (Enter your answer in kg/s.)
If a rocket engine ejects gases at a rate of 29 kg/s, how fast must the gaseous exhaust be moving if the thrust produced is sufficient to allow a 2.7 x 105 kg rocket to rise slowly from the earth when aimed straight up? Express your answer in km/s.
