A car is parked on a cliff overlooking the ocean on an incline that makes an angle of 24.0° below the horizontal. The negligent driver leaves the car in neutral, and the emergency brakes are defective. The car rolls from rest down the incline with a constant acceleration of 3.82 m/s2 for a distance of 70.0 m to the edge of the cliff, which is 40.0 m above the ocean.
(a) Find the car's position relative to the base of the cliff when the car lands in the ocean.
(b) Find the length of time the car is in the air.
A container of volume 23 cm3 is initially filled with air. The container is after that evacuated at 0oC to a pressure of 30 mPa. How many molecules are in the container after evacuation if we suppose that air is an ideal gas.
Find out the minimum horizontal velocity magnitude of the acceleration of the blocks
If the 2 kg mass slides on a horizontal frictionless surface, what is the speed of the mass 4 kg while it has fallen a distance 0.4 m downward from its rest position.
A sample of paramagnetic material containing \(10^{25}\) atoms is placed in an external field magnetic field of 1 tesla at room temperature
A rectangle with a length L, and width L/2 has a surface charge density of 3.1mC/m^2. Determine the integral that would give you the electric field at a height h above the middle of the long edge.
What is the magnitude of the acceleration of an electron at a point where the electric field has magnitude 6656 N/C and is directed due east?
How many liters of gasoline would give the same mechanical energy given that each liter provides 8.50x10^6 J of mechanical energy.
In a local bar, a customer slides an empty beer mug down the counter for a refill. The height of the counter is 1.20 m. The mug slides off the counter and strikes the floor 0.60 m from the base of the counter.
A major-league catcher gloves a 92 {rm mi}/{rm h} pitch and brings it to rest in 0.15 {rm m}.If the force exerted by the catcher is 803 {rm N}, what is the mass of ball.
A bullet of mass 4.3 g is fired horizontally into a 8.60 kg wooden block at rest on horizontal surface. The coefficient of kinetic friction between block and surface is 0.13.
A long string is wrapped around a 6.60 diameter cylinder, initially at rest, that is free to rotate on an axle. The string is then pulled with a constant acceleration of 1.70 until 1.30 of string has been unwound. If the string unwinds without slippi..
