When a multi-stage booster is fired into space, the mass of the booster changes as the fuel is burned during flight. Discuss how the change in mass influences the acceleration of the booster. When should the first stage of the booster be jettisoned (at maximum velocity, maximum acceleration, maximum altitude, or at some other time)? Justify your selection and give your own example of how mass influences acceleration and describe the process as it happens in your example.

1. A marble is fired into the air at 12m/s at an angle of 35° from vertical. It lands 1.25 m lower than its launch height. What is the maximum height that it reaches above its landing location? When does it reach this height? When does it land? What is its velocity (speed and direction) when it lands? Max height Time at max height = Time of landing- Velocity at landing - 2. The Space Shuttle used to fly...

1) A space shuttle without fuel weighs 75,000 kg. The international space station is 408 km in the sky. It will reach this altitude in roughly 450 seconds. Neglecting the weight of fuel (which is a complex calculation as it is used up by the flight), as well as any reduction to the force of gravity at that height, calculate: (A) The potential energy of the space shuttle at the height of the ISS (B) the work needed to get...

Question 11 5 pts You perform an experiment in which you pull a carton a frictionless air track with a hanging mass. For the first run you place 5 slotted 20g masses on the car. You make 5 more runs. Each time removing 1 slotted mass and adding it to the hanger. You are venifying Newton's Second Law. What value are you holding constant? Omo ( Mm) ( Mm) Question 12 5 pts A rocket is designed to have constant...

A bullet with mass 25g and initial horizontal velocity 320m/s strikes a block of mass 2kg that rests on a frictionless surface and is attached to one end of a spring. The bullet becomes embedded in the block. The other end of the spring is attached to the wall. The impact compresss the spring a maximum distance of 25cm. After the impact, the block moves in simple harmonic motion. What is the frequency of the oscillation? Sketch graphs for the...

A physic student sets out to experiment on the effect of drag forces on a ball of mass m by giving the ball an initial velocity nu_0 upwards and then downwards as describe below. In both cases, the ball experiences a force of air resistance whose magnitude is given by F = -k nu Where k is a positive constant. The positive direction for all vector quantities is taken to be upwards. Express all algebraic answers in terms of m....
