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 cord is wrapped around the rim of a solid uniform wheel 0.300 in radius and of mass 7.80 . A steady horizontal pull of 40.0 to the right is exerted on cord, pulling it off tangentially from the wheel. The wheel is mounted on frictionless bearing..
The stone is whirled in a horizontal circle on a frictionless tabletop; the other end of the string remains fixed. Find out the maximum speed the stone can attain without breaking the string.
The aurora is caused when electrons and protons, moving in earth's magnetic field of 5x10^-5 T, collide with molecules of the atmosphere and cause them to glow. What is the radius of the circular orbit for (a) an electron with speed 1.0×10^6 and (b) ..
A 6.5×10-25-kg particle is vibrating with simple harmonic motion with a period of 5.0×10-6 s and a maximum speed of 6.00×102 m/s. Find the Maximum displacement of the particle.
find the angular speed after the grindstone. what must be its minimum mass so that material on its surface remains in place during the rapid rotation.
the diameter of the vessel is 5.6 mm. In a 0.60-T magnetic field illustrate what is the magnitude of the voltage that is measured with the electrodes in the drawing?
The police officer, knowing that the coefficient of kinetic friction between tires and road is 0.80, compute the speed of the sports car at impact.
A chair of weight 74.0 N lies atop a horizontal floor; the floor is not frictionless. You push on the chair with a force of F = 47.0 N directed at an angle of 41.0^circ below the horizontal and the chair slides along floor.
A car travelling at 120 strikes a tree. The front end of the car compresses and driver comes to rest after travelling 0.900.
What is the terminal speed at which the bar falls.
A rifle fires a 2.39 10-2-kg pellet straight upward, since the pellet rests on a compressed spring that is released when the trigger is pulled. The spring has a negligible mass and is compressed by 9.17 10-2 m from its unstrained length. The pellet r..
calculate the average acceleration in m/s^2 (meter per second square), using a coordinate system with the X axis in the direction of the car's original motion and the Y axis toward the side of the road to which the car skids.
