Problem 3. Consider a rocket with total initial mass m Exactly half of m is fuel, which is expelled from the rocket at a constant rate k (mass per unit time) and with speed with respect to the rocket. There is a uniform gravitational field g downwards, and the motion of function of time be r(t). The the rocket is entirely vertical. Let the height of the rocket as a the ground (at rocket is at rest on 0) and...

39. Rocket Motion Suppose a small single-stage rocket of total mass m) is launched vertically, the positive direction is upward, the air resistance is linear, and the rocket consumes its fuel at a constant rate. In Problem 22 of Exercises 1.3 you were asked to use Newton's second law of motion in the form given in (17) of that exercise set to show that a mathematical model for the velocity v(t) of the rocket is given...

Newton's version of Kepler's Law Force Example Use what we know about the earth's orbit to estimate the mass of the sun. For this problem we can use Newton's form of Kepler's law Solving for the sum of the masses we get to use this law we need all our values to be kilograms, meters, and seconds. a 1AU-149.6x10P m and p- 1 year (365.25 days/year)(24 hours/day)(3600 seconds/hour)-3.15x 10" sec. Placing these values in to our equation we get M+...

1. A firework (small rocket) whose shell has a mass of m 12kg was initially on the ground before being launched to a height of 100m above the ground at which point its horizontal displacement from its starting position is 17.6m. At this location its speed is 68m/s and it's at an angle relative to (and above) the horizontal of 80 as depicted in the diagram below. Once it reaches this height it goes off and its shell splits into...

A light cable is wrapped around a solid cylinder with mass M = 1.50 kg and radius R = 0.20 m as shown in the figure below. The cylinder rotates with negligible friction about a stationary horizontal axis. The free end of the cable is tied to a block of mass m = 0.50 kg. The block, initially at rest, is released at a height h = 1.00 m above the floor. As the block falls, the cable unwinds without...

Hand In Problem 2 A solid globe of mass M and radius R can rotate about its axis. A block of mass m is attached by a massless-string/pulley system as shown. As the block falls it causes the globe to spin. If the block starts at rest, at what speed does the block hit the ground after it falls a distance h? ' State your answer in terms of the given variables: M, R, m, h and g. Solve this...

Bridging Problem: Oscillating and Rolling Two uniform, solid cylinders of radius R and total mass M are connected along their common axis by a short, light rod and rest on a horizontal tabletop (Figure 1). A frictionless ring at the rod's center is attached to a spring of force constant k, the spring's other end is fixed. The cylinders are pulled to the left a distance I, stretching the spring, then released from rest. Due to friction between the tabletop...
