Q. A camel sets out to cross the desert, which is 21.9 km wide in the north-south direction. The camel walks at the unifrom speed 3.51 km/hr along a straight line in the direction 49.6° north of East.
A) How long will it take the camel to cross the desert? Answer in units of hr.
B) Calculate the camel's eastward displacement while he crosses the desert. Answer in units of km.
An air molecule is moving at a speed of 455 m/s. How many meters would the molecule move throughout 7ms (milliseconds) if it didn't collide with any other molecules.
An ocean liner leaves New York City and travels 12.0° north of east for 111 km. How far east and how far north has it gone? In other words, what are magnitudes of the components of the ship's displacement vector in the directions.
The coefficient of static friction
A car is stopped for a traffic signal. When the light turns green, the car accelerates, increasing its speed from 0 to 4.50 m/s in 0.852 s. What are the magnitudes of the linear impulse and the average total force experienced by a 65.0 kg passenger i..
A 1500 car travelling at 26 suddenly runs out of gas while approaching the valley that looks like an inverted hump. 12m at the left where the care runs out of gas and 19 m at the right were it is headed. What will be the car's speed as it coasts into..
A 72 person stands on a uniform ladder 4.5 long, that weighs 75. The floor is rough; hence, it exerts both a normal force, and a frictional force, on the ladder. The wall, on the other hand, is frictionless; it exerts only a normal force.
An undamped oscillator has period 0 = 1.000 seconds, but I now add a little damping so that its period changes to 1 = 1.001 seconds. What is the damping factor ? By what factor would the amplitude of oscillation decrease after 10 cycles.
A thin rod consists of two parts joined together. One third of it is silver and two-thirds is gold. The temperature decreases by 24C°.
What minimum heat is needed to bring 230g of water at 20 degrees C to the boiling point and completely boil it away.
