Q. Car 1 has a mass of m1 = 65 multiplied by 103 kg and moves at a velocity of v01 = +0.76 m/s. Car 2, with a mass of m2 = 92 multiplied by 103 kg and a velocity of v02 = +1.5 m/s, overtakes car 1 and couples to it. Neglect the effects of friction in your answer.
Determine the velocity of their center of mass before the collision
An electric field of 8.55x10^5 V/m is desired between two parallel plates, each of area 35.00 cm^2 and separated by 2.45mm of air. What charge should be on each plate.
The block is acted upon by its weight w=200lb, a horizontal force Q=600 lb and pressure P exerted by the inclined plane. The resultant R of these forces is up and parallel to the incline there by sliding the block up it. Establish P and R.
NASA sends a satellite to another planet by placing the satellite in a Keplerian orbit (around the sun) such that the perihelion is at the radius of the Earth's orbit (1 AU) and the aphelion is at the radius of the planet's orbit. Most of the trip is..
A very long solenoid with a circular cross section and radius r= 8.1cm with n= 1.90E+4 turns/m has a magnetic energy density uB= 5.70 mJ/m3. What is the current in solenoid.
A horizontal uniform bar of mass 2.7 and length 3.1 is hung horizontally on two vertical strings. String 1 is attached to the end of bar, and string 2 is attached a distance 0.7 from other end. A monkey of mass 1.6 walks from one end of the bar to th..
A tank with vertical walls, 2m wide and 2m long and 2.5 m high, is filled with 4800 litres of water (density 1000 kg/m3) and 3200 litres of light oil (density 900 kg/m3). compute the magnitude and location of the resultant force on each of the ver..
A 10.60 weather rocket generates a thrust of 220. The rocket, pointing upward, is clamped to the top of the vertical spring. The bottom of the spring, whose spring constant is 450, is anchored to the ground.
Is kinetic energy consumed in the third type of collision studies? Classify the three collision kinds as elastic, inelastic, or completely inelastic.
An object at rest explodes into three pieces of equal masses. One moves east at 23 m/s, while the second piece moves northwest at 14 meter per second. Find the velocity of the third piece?
Compute the magnitude of the average acceleration
While on vacation you rent a moped and go cruising around a tropical island. If you take a 10.0° banked curve with a radius of 15.0 meters at 12.0 m/s, what is the minimum coefficient of static friction between your tires and road to keep the tires f..
An ideal gas at 20 C consists of 2.2 X 10^{22} atoms. 4.3 J of thermal energy are removed from the gas. What the new temperature in C.
