Problem 1,2,3.
MEEN 2302 Sum 2019 HW1 Name Problem 1 12-4. Traveling with an initial speed of 70 km/h, a car accelerates at 6000 km/h2 along a straight road. How long will it take to reach a speed of 120 km/h? Also, through what distance does the car travel during this time? Problem 2 An object freely falling through the atmosphere has an acceleration a -32.2 [1- (v'/160,000)] ft/sec', empirically determined. This equation accounts for drag from earth's atmosphere. If...

this project discovers the free-falling velocity of skydivers
before the parachutes are opened using the laws of physics and
calculus. you can ignore the wind in the horizontal direction. let
m be the mass of a skydiver and the equipment, g be the
acceleration due to gravity. the free-falling velocity of a
skydiver, v(t), increases with time. the force due to the air
resistance is correlated with the velocity, that is, Fr=kv^2, where
k>0 if called the drag constant related...

1. [25 points) Idealized frictionless free fall of an object that is dropped from being at rest at i = 0. For the following question, to model the free fall of a falling rock, assume the usual idealizing simplifications for solving "free fall" problems. Consider the following experiment. A rock with a mass of m= 2 kg is dropped at the time t = 0 from a height of 140 m above ground. Assume that the rock is simply dropped...

Vibrational Motion Introduction If an object is following Hooke’s Law, then Fnet = -kx = ma Since acceleration is the second derivative of position with respect to time, the relationship can be written as the differential equation: kx = m δ2xδt2/{"version":"1.1","math":"<math xmlns="http://www.w3.org/1998/Math/MathML"><mi>k</mi><mi>x</mi><mo> </mo><mo>=</mo><mo> </mo><mi>m</mi><mo> </mo><mfrac bevelled="true"><mrow><msup><mi>δ</mi><mn>2</mn></msup><mi>x</mi></mrow><mrow><mi>δ</mi><msup><mi>t</mi><mn>2</mn></msup></mrow></mfrac></math>"} Methods for solving differential equations are beyond the scope of this course; in fact, a class in differential equations is usually a requirement for a degree in engineering or physics. However, the solution to this particular differential...
