Q. Far in space, where gravity is negligible, a 425 kg rocket traveling at 75 m/s fires its engines. The mass lost by the rocket during these 30 s is negligible. The impulse is 15000 Ns. At what time does the rocket reach its maximum speed and what is the maximum speed?
Q. How much force is required to hold a 7.0 cm diameter hose delivering 440 L/min through a 0.73cm diameter nozzle?
The atomic mass of copper is 64 g/mole, and the density of copper is 8.9 g/cm3.
suppose that the cross section of the hose opening is circular with a radius of 1.5 centimeters.
What centripetal force does an 80-kg passenger experience when seated 12 m from the center of the Ferris wheel whose angular speed is 0.50 rad/s.
A point source of light is 200 cm below the surface of a body of water. Find out the diameter of the circle at the surface through which light emerges from the water.
An airplane is flying with a velocity of 90 m/s at an angle of 25 above the horizontal. When the plane is a distance 126 straight above a dog that is standing on level ground, a suitcase drops out of the luggage compartment.
The two parallel plates in the figure below are 2.0 cm apart and the electric field strength between them is 2.1 104 N/C. An electron is launched at a 45° angle from the positive plate. What is the maximum initial speed v0 the electron can have witho..
compute the mean scattering cross-section at a frequency of 5 MHz of a distribution of air bubbles of 3 μm mean radius, assuming a Gaussian size distribution of a variance of 1 μm and 1.5 μm. The total damping constant is 1.0.
A 0.27 kg rock is thrown perpendicularly upward from the top of the cliff that is 32 m high. When it hits the ground at the base of cliff, the rock has a speed of 29 m/s. suppose that air resistance can be ignored, find out A) initial speed of the ro..
