A 5.01E+4 kg space probe is traveling at a speed of 12600 m/s through deep space. Retrorockets are fired along the line of motion to reduce the probe's speed. The retrorockets generate a force of 3.85E+5 N over a distance of 2420 km. What is the final speed of the probe?
A ball is thrown at an angle of 52.5 degree above the horizontal at a speed of 8.2 m/s. What is the vertical component of the ball's velocity
A steel cable with total length 59 m and mass 110 kg is connected to two poles. The tension in the cable is 1,260 N, and the wind makes the cable vibrate with a frequency of 2 Hz. Calculate the wavelength of the resulting wave on the cable
If the initial temperature of the horseshoe is 600?C, and initial temperature of the water is 40?C, what is the equilibrium temperature of the system? Suppose no heat is exchanged with the surroundings.
Illustrate what is the basis for the industry's legal duty to the surrounding community? In other words, illustrate what is the legal source of the industry's legal duty?
A wooden raft has a mass of 65 kg. When empty it floats in water (density 1000 kg/m3) with 41percent of its volume submerged. What mass of sand can be put on the raft without it sinking.
An object acted on by three forces moves with constant velocity. One force acting on the object is in the positive x direction, Find the direction of the third force acting on the object
Light travels at a constant speed of 3.0×108 m/s in a vacuum. (a) It takes light about 1.3 seconds to travel from the Earth to the Moon. Estimate the distance of the Moon from the Earth's surface, in meters.
Neglect air resistance, as well as any energy absorbed by the pole, and clerify her altitude as she crosses the bar.
What is the weight of the staging. A highway curve with radius 800 is to be banked so that a car traveling 56.0 will not skid sideways even in the absence of friction. At what angle must the curve be banked.
A 4.70 kg mass causes a vertical spring to stretch 0.850 meters. The spring is after that stretch and extra 0.270 meters and release (as a stopwatch starts) causing the spring and mass to oscillate.
An electric motor with a power of 3W is used to lift a .2 kg mass a height of 0.5 meters in 3.0 seconds, since total energy must be conserved
At t = 0, a particle leaves the origin with the velocity of 9 m/ s in the positively direction and moves in the x y plane with a constant acceleration of (2.0i - 4.0j) m/ s2. At the instant the x coordinate of the particle is 15m, what is the spee..
