An advertisement claims that a particular automobile can "stop on a dime." What net force would actually be necessary to stop an automobile of mass 920kg traveling initially at a speed of 56.0km/h in a distance equal to the diameter of a dime, which is 1.80cm ?
A spring with an unstrained length of 0.069 m and a spring constant of 2.7 N/m hangs vertically downward from the ceiling. A uniform electric field directed vertically upward fills the region containing the spring.
Suppose a 63.00 kg boy and a 50.00 kg girl use a mass less rope in a tug-of-war on an icy, resistance-free surface. If the acceleration of the girl toward the boy is 3.00 m/s2, find out the magnitude of the acceleration of the boy toward girl.
An ocean liner leaves New York City and travels 20.0° north of east for 199km. How far east and how far north has it gone? In other words, what are the magnitudes of components of ship's displacement vector in the following directions.
What is the magnitude of the torque about the point where the beam is bolted into place.
find the arrow's initial speed? How long did it take for the arrow to first reach a height of 17.5 m above its launch point.
An object with a net charge of 44 µC is placed in a uniform electric ?eld of 554 N/C, directed vertically. The acceleration of gravity is 9.81 m/s^2. What is the mass of this object if it ?oats in this electric ?eld?
explain the separation between the two sources. What is the displacement of the car between 3 P.M. and 6 P.M.
A jogger travels a route that has two parts. The first is a displacement of 2.00 km due south, and the second involves a displacement that points due east.
The sensor in the torso of a crash-test dummy records the magnitude and direction of the net force acting on the dummy. If the dummy is thrown forward with a force of 570N while simultaneously being hit from the side with a force of 2400-N, what f..
A block with mass m = 15kg rests on a frictionless table and is accelerated by a spring with spring constant k = 4234N/m after being compressed the distance x1 = 0.536m from the spring's unstretched length. The floor is frictionless except for a roug..
Tam walks with the velocity of 1.8 m/s west. He does so while riding on a conveyor belt that moves at a velocity of 0.7 m/s west. What is Tam's velocity.
Billy Dee notes that her favorite record rotates at 34 rev/min. At what speed does the point on the record touching the stylus (needle) move when the stylus (needle) is 5.9 cm from the center?
