On a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. It strikes a red glider that has mass 0.600 kg and that is initially at rest. After the collision, the blue glider is moving to the left with a speed of 2.00 m/s.
(a) What are the magnitude and direction of the velocity of the red glider after the collision?
A house has a floor area of 113 m2 and an outside wall that has an area of 26 m2. The earth's magnetic field here has a horizontal component of 3.0 multiplied by 10-5 T that points due north and the vertical component of 4.9 multiplied by 10-5 T p..
What is its velocity when it reaches the maximum height.
From another measurement, you have found that velocity of the jumper's center of mass has only a y component of v2=2.5 m/s as the jumper's feet leave the floor.
Two identical positive charges exert a repulsive force of 6.4* 10^-9 N when separated by a distance of 3.8*10^-10 m. find the charge of each.
If you weigh 690 N on the earth, what would be your weight on the surface of a neutron star that has the same mass as our sun and a diameter of 25.0 km.
Julie throws a ball to her friend Sarah. The ball leaves Julie's hand a distance 1.5 meters above the ground with an initial speed of 22 m/s at an angle 63 degrees, What is the distance between the two girls
The coefficient of kinetic friction is 0.400. Illustrate what should be the magnitude of P, so that the net work done by it and the kinetic frictional force is zero?
In an electricity experiment, a 0.800g plastic ball is suspended on a 51.0cm long string and given an electric charge. what is the tension of the string
State the condition that is necessary for a charge to move in a wire. Relate the definition of electric current to the units of current. Explain the cause of resistance and how the resistance of a wire can be determined.
A 36.0 g bullet moving at 478 m/s strikes a 3.7 kg bag of flour that is on ice, at rest. The bullet passes during the bag, leaving at 255 m/s. How fast is the bag moving when the bullet exits.
