Two spheres are launched horizontally from a 1.0 meter high table. Sphere C has a mass of 1.6 kilogram and is launched with an initial speed of 5.0 m/s. Sphere D has a mass of 0.4 kilogram and is launched with an initial speed of 3.5 m/s.
(a) Compute the times for each sphere to hit the floor.
tA = s
tB = s
(b) Determine the distances that each travels from the edge of the table.
xA = m
xB = m
After being created in a high-energy particle accelerator, a pimeson at rest has an average lifetime of 2.60*10-8 s. Traveling at a speed very close to thespeed of light, a pi meson travels a distance of 105 m before decaying. How fast is it moving..

A 500 kg vehicle is cruising down the highway at 30 m/s when the driver creates an average force of 700 N by stepping on the gas. How much work was done by the vehicle during the .50km of acceleration
If a person radiates about 65.00 W of power at room temperature, how long does it take for a person to radiate away the energy acquired by consuming a 230 Calorie donut.
A beam of laser light with a wavelenth of ? = 690.00 nm passes through a circular aperture of diameter a = 0.133 mm. What is the angular width of the central diffraction maximum
In each of the four scenarios to the right, a large bat lets out a short burst of ultrasonic sound, which the smaller bat hears a moment later. If the large bat flies at 14.60 m/s and the small bat flies at 4.520 m/s, rank the frequency that the s..
A sled with mass 8.00 kilogram moves in a straight line on a frictionless horizontal surface. Use the work-energy theorem to determine the force acting on the sled
To focus a camera on objects at different distances, the converging lens is moved toward or awayfrom the film, so a sharp image always falls on the film.
An electric wire that has a mass of 5 kg for a 20m length is strung between two poles 20 m apart. What must be the tension in the wire if it is to take .80 seconds for a pulse to travel along the wire from one pole to the other.
assume the current in the coaxial cable, see the figure , is not uniformly distributed, but instead the current density varies linearly with distance from the center: for the inner conductor and for the outer conductor. Each conductor still carrie..
A 4.0- m-long iron bar of uniform cross section is held perpendicular to the wall by a wire from the end of the bar to the wall, What is the tension in the wire if the iron bar weighs 300 N and the wire is 5.0 m long
