An object of mass 4.15 kg undergoes an acceleration of 3.5 m/s^2 for a period of...

An object of mass 4.15 kg undergoes an acceleration of 3.5 m/s^2 for a period of 7.0 seconds. It then undergoes an acceleration of -4.2 m/s^2 for a period of 18.0 seconds. If the initial velocity of the object is 4.01 m/s and it first experiences the acceleration when it is at the origin, plot by hand on graph paper (to scale) the force, velocity, and position graphs as functions of time. Explain why your graphs look the way they...

Obesity if dened as a body mass index (BMI) of 30 kg/m^2 or more. A 95% confidence interval for the percentage of U.S. adults aged 20 years and over who were obese was found to be 16.5% to 27.5%. What was the sample size used?

The figure gives the acceleration of a 4.0 kg particle as an applied force moves it...

The figure gives the acceleration of a 4.0 kg particle as an applied force moves it from rest along an x axis from x = 0 to x = 9.0 m. The scale of the figure's vertical axis is set by as = 8.0 m/s2. How much work has the force done on the particle when the particle reaches (a) x = 4.0 m, (b) x = 7.0 m, and (c) x = 9.0 m? What is the particle's speed...

Mass m = 0.1 kg moves to the right with speed v = 0.54 m/s and...

Mass m = 0.1 kg moves to the right with speed v = 0.54 m/s and collides with an equal mass initially at rest. After this inelastic collision the system retains a fraction = 0.9 of its original kinetic energy. If the masses remain in contact for 0.01 secs while colliding, what is the average force in N between the masses during the collision? Hints: All motion is in 1D. Ignore friction between the masses and the horizontal surface. You...

A spring with a mass of 2 kg has a damping constant 14 kg/s. A force of 3.6 N is required to keep the spring stretched 0.3 m beyond its natural length. The spring is stretched 0.7 m beyond its natural length and then released. Find the position of the mass at any time t. (Assume that movement to the right is the positive x-direction and the spring is attached to a wall at the left end.) What is x(t)?

The only force acting on a 8 kg body as it moves along the x axis...

The only force acting on a 8 kg body as it moves along the x axis varies as shown in the figure. The velocity of the body at x = 0 is 8.0 m/s. What is the kinetic energy of the body at x =3.0 m? At what value of x will the body have a kinetic energy of 244.40 J? What is the maximum kinetic energy attained by the body between x = 0 and x = 5.0 m

Ball 1 with mass 1 kg moves at constant velocity to the right at 3.0 m/s,...

Ball 1 with mass 1 kg moves at constant velocity to the right at 3.0 m/s, towards Ball 2 with mass 2 kg moving to the right at 1.5 m/s. 1 and 2 collide elastically. What is the final velocity of 1 and 2?

Since force is m*a, it has units of kg m/s^2 . Energy has units of kg m^2/s^2. Thus it appears that by lazy dimensional analysis that a force times a distance will have units of energy. This turns out to be the formula to calculate work. Note also that kg m^2/s^2 looks like mv^2. Here if we use dimensional analysis, we would *almost* find the formula for kinetic energy. We'd be off by a factor of two since KE=1/2 mv^2....

An object of mass m=4.00 kg is acted on by a 2-D force of the form: F=C(x^2y^2,xy^3), where the coordinates are given in meters and the constant C=62.4 N/m^4. a.) calculate the work that F does on an object if it moves from the origin to the point (2,2) along a straight line path (the shortest possible path). b.) calculate the work that F does on the object if it moves between the two same points, but along a different...

An object with a mass of 4.15 kg undergoes an acceleration of 2.7 m/s2 for a period of 8.0 s. It then undergoes an acceleration of -3.2 m/s2 for a period of 20.0 s If the initial velocity of the object is 6.01 m/s and it first experiences the acceleration when it is at the origin, plot by hand on graph paper (to scale) the force, velocity, and position as functions of time. Explain why your graphs look the way...
