Suppose that the position of a falling object is governed by the following differential equation: where c a first-order drag coefficient 12.5 kg/s, m mass 70 kg, and g gravitational acceleration = 9.81 m/s2. Use the shooting method to solve this equation for the boundary conditions: x(0) = 0 x( 12) = 500

Does gravitational acceleration remain constant even if there is initial velocity? (We conducted an experiment to get the acceleration of an object by dropping it. The first trial was in free fall condition while second trial was with initial velocity on the object. Our data showed that both trials had an acceleration near 9.8 m/s2)
When an object falls in Earth's gravitational field (think of a skydiver jumping from an airplane or a marble falling in a tank of oil)
When an object falls in Earth's gravitational field (think of a skydiver jumping from an airplane or a marble falling in a tank of oil), it accelerates due to the force of gravity. If gravity were the only force acting on the object, then all objects-elephants and feathers alike would fall at the same rate. But gravity is not the only force present. Moving objects also experience resistance or friction from the surrounding medium; it would be air resistance for...

1. By how much does the gravitational force between two masses change when the distance between two is halved: a)1/4 b) 4 c) 2 d) 1/2 2. If the mass of a planet is halved, what happens to the acceleration due to gravity at the surface of the planet? a) Doubled b) Halved c) Tripled d) No change 3. If an object is moving in circular motion at a speed, what direction does the centripetal force act? a) Up b)...

A student developed an experiment to measure the gravitational acceleration. In this experiment, two photogates were used to measure the time it takes the object to fall from rest (at the first photogate) and reach the lower gate. The student recorded time (t) and the distance (y) between the two photogates as shown in the following table: t (s) y(m) 0.141 0.100 0.199 0.200 0.244 0.300 0.281 0.400 0.315 0.500 0.345 0.600 0.372 0.700 Use Excel to plot y versus...

you want to measure the gravitational acceleration at your location. since g does not vary significantly over the surface of the earth you will have take very precise measurements you make a simple pendulum by typing a 55 g hex nut to a string of length 1.500 m. you pull the mass to the side and release it to let it oscillate observing that it takes 2.454 s for the mass to return to its original position what is the...

Problem 1. The working distance of myosin II proteins is 5 nm, as measured by several in vitro assays. Does this working distance depend on the contraction speeds of muscles in vivo? If it does, how do the contraction speeds of muscles affect the working distance of individual myosin proteins? If it doesn’t, explain why?
