An outfielder makes a throw directly to home plate which is 94.2m away. The ball leaves his hand with a speed of 36m/s at a height of 1.8m from the ground and making an angle of 19* with the horizontal. Determine where the ball lands relative to home plate. ( a sketch would help me tremendously)
Coherent light from a sodium-vapor lamp is passed through a filter that blocks everything except for light of single wavelength. It then falls on two slits separated by 0.410 . In resulting interference pattern on a screen 2.10 away, adjacent bri..
One fragment, whose speed immediately after the explosion is zero, falls vertically. Illustrate what is the horizontal speed of the other fragment?
A particle with a charge of ?1.0 ?C and a mass of 2.4 10-6 kg is released from rest at point A and accelerates toward point B, What is the potential difference VB ? VA between A and B
Neptune has a mass 17.20 times larger than that of Earth and a radius 3.88 times larger. A person weighing 140 lb on the Earth would weigh how much on Neptune.
In a refrigerator the working fluid remains a gas throughout the cycle. Its working may be described in a greatly simplified form as a sequence of four steps as follows: 1 The fluid passes through the refrigerated compartment, where its temperatur..
Given an isothermal expansion of gas from 1.0 to 2.0 cubic meters in a piston-cylinder arrangement where pressure varies according to P= 1.2 atm -.062 atm/ m^3 V, How much thermal energy was transferred
A steel wire strung between two supports is initially horizontal when there is no tension on it. When a 9.5 kg painting is hung on the wire, the wire makes a 25° angle to the horizontal, as shown. Illustrate what is the diameter of the wire?
A race car has a mass of 701 kg. It starts from rest and travels 35.0 m in 3.0 s. The car is uniformly accelerated during the entire time. Illustrate what net force is exerted on it?
Coherent light with wavelength 609nm passes through two very narrow slits, and the interference pattern is observed on a screen a distance of 3- {rm m} from the slits. The first-order bright fringe is a distance of 4.84 {rm mm} from the center of ..
The engine weighs 4500 newtons and it is lifted 1.5 meters up by the block and tackle system. The mechanic must apply a force of 225 newtons while pulling a total of 37.5 meters of chain by the block and tackle pulley system. What is the work done..
How much work is needed to move a 120-kg refrigerator.
Two ideal gases have the same mass density and the same absolute pressure. One of the gases is helium (He), and its temperature is 180 K. The other gas is neon (Ne). Illustrate what is the temperature of the neon?
