The kinetic energy in joules of an automobile weighing 2135 lb and traveling at 55 mph is 2.9 x 105.
it strikes the ground at a velocity of 17.9 ft/s
Hydrostatic weighing, also called underwater weighing, involves being weighed underwater.requires one to be completely submerged in water for a few seconds. ref. http://www.wisegeek.com/what-is-hydrostatic-weighing.htm
pour the sample on the weighing paper
shopkeepers do this by writing 1 kg on a weigh which is actually of half kg and when they balance it they take the money of 1 kg, but in real they have given only half kg
The kinetic energy in joules of an automobile weighing 2135 lb and traveling at 55 mph is 2.9 x 105.
A disc weighing 2 kg rolls without slipping over a horizontal plane with a velocity 4 ms1 Find the kinetic energy of the disc?
it strikes the ground at a velocity of 17.9 ft/s
if a truck weighing 5000 lbs traveling 15 mph hits an object , what is the pressure at impact?
A pellet weighing 7.9 grams can not exceed 826/FPS See the link below
KE=(1/2)mv246080 Joules
the normal force is acting on the sled-- it's what keeps the sled from falling through the slope
You can use De' Broglie's equation. I think it is wavelength = plank's constant/mass of the object *velocity.velocity is unknown in this case, m= 154g and wavelength is 0.450*10-90.450*10-9 = look up the value of plank's constant/ 0.145 kg* Velocity.Rearrange the equation to get velocity of an object.
Momentum = mass * velocity Momentum of 60kg woman = 60*5= 300 kgm/s Therefore speed of 50kg woman = 300/50 = 6 m/s
Obtain an appropriate weighing device. Make sure the device is calibrated properly. Perform the weighing by placing the object on top of the weighing device.
