In compressing the spring in a toy dart gun, 0.6 J of work is done. When the gun is fired, the spring gives its potential energy to a dart with a mass of 0.08 kg.
(a) What is the dart's kinetic energy as it leaves the gun?
(b) What is the dart's speed?
Suppose you have an electric hot water heater for your house which is an aluminum cylinder which has a 0.6 m radius and is 1.2 m high. The walls are 1.0 cm thick.
A car crashes into a wall at 25 m/s and its contents are brought to rest in 0.1s. display that the average force exerted on a 75-kg test dummy by the seat belt is more than 18,000 N.
Calculate the buoyant force of water on a completely submerged sample volume of 3.4 meter^3.
A car drives north at 42 mi/h for 10 {rm min} and then turns east and goes 5.0 {rm mi} at 62 mi/h. at last, it goes southwest at 30 mi/h for 6.0 {rm min}.
An aluminum rod is clamped one quarter of the way along its length and set into longitudinal vibration by a variable-frequency driving source. The lowest frequency that produces resonance is 4300 Hz. The speed of sound in an aluminum rod is 5100 m..
A cargo plane in flight lost a package because somebody forgot to close the rear cargo doors. You are on the team of safety experts trying to analyze what happened, Calculate the time at which the package fell off the back ramp
A person carries a long pole of mass 10kg and length 3.40 m at the angle of 60 degrees. Find the magnitude of the torque on the pole by reason of gravity.
A vertical scale on a spring balance reads from 0 to 225. The scale has the length of 11.5 from the 0 to 225 reading. A fish hanging from the bottom of the spring oscillates perpendicularly at a frequency of 3. Ignore the mass of the spring, what ..
In a carnival they often have a large r = 16 m, cylinder which people stand against the outer wall while it rotates with some velocity, What is the minimum velocity of the cylinder to make someone "stick" to the wall in m/s
3 point charges are placed on the x-y plane: a +50.0 nC charge at the origin, a -50.0 nC charge on the x-axis at 10.0 cm, Find the total electric force on the +150 nC charge due to the other two
Evaluate (a) the acceleration of each object, (b) the tension in the string, and (c) the coefficient of kinetic friction between m2 and the incline.
Determine the net Force (magnitude and direction) acting on wire 3 due to wires 1 and 2 for currents of 10A. Each wire has a horizontal length of 50 cm and each wire is seperated by a distance of 2 cm
