A) Estimate the force with which a karate master strikes a board if the hand's speed at time of impact is 13.7 m/s , decreasing to 0.832 m/s during a constant time of 0.00119 s with the board. The mass of coordinated hand and arm is 1.15 kg .
B) Estimate the shear stress if this force is ex- erted on a 0.412 cm -thick pine board that is 13.7 cm wide.
A projectile is fired at 60.0 o above the horizontal. Its initial speed is equal to 150.0 m/s. Like most problems in this class (2010), ignore the effects of air unless told otherwise
Two football players are moving toward each other in a straight line. Number 56 has a mass of 120 kg, Determine the velocity (magnitude and direction) of players, after the collision, before they hit the ground
A race car has a mass of 718 kg. It starts from rest and travels 45.0 m in 3.0 s. The car is uniformly accelerated throughout the entire time. What net force is exerted on it.
The light shining on a diffraction grating has a wavelength of 494 nm (in vacuum). How many lines per centimeter does the grating have
An outboard motor for a boat is cooled by lake water at 14.7 degC and has a compression ratio of 14.1, Calculate efficiency of the engine's Otto Cycle
A blob of iron sinks form the surface of earth to the center. Assume the blob does not transfer any energy to its surroundings. Assume the density of earth is uniform.
A typical nuclear power plant converts 0.01% of the mass of its fuel into energy through nuclear reactions. How much fuel would be needed to power an average city for one day
One way to measure on another planet or moon by remote sensing is to measure how long it takes an object to fall a given distance. A lander vehicle on a distant planet records the fact that it takes 3.17 for a ball to fall freely 11.26.
Suppose the projectile is traveling 85.0 m/s at its maximum height of y = 272 m. Explain how much work has been done on the projectile by air friction?
As a 13,800 kg jet plane lands on an aircraft carrier, its tail hook snags a cable to slow it down. what was the plane's landing speed
The calorimeter is constructed of a material that has a specific heat of 0.10 cal/ g. ^{circ}C. When equilibrium is reached, what will be the final temperature.
Does papillary muscles contract after the other ventricular muscles so that they can take up the slack on the chordae tendineae before the full force of ventricular contractions sends blood against the AV valve flaps.
