Bungee Man is a superhero who does super deeds with the help of Super Bungee cords. The Super Bungee cords act like ideal springs no matter how much they are stretched. One day, Bungee Man stopped a school bus that had lost its brakes by hooking one end of a Super Bungee to the rear of the bus as it passed him, planting his feet, and holding on to the other end of the Super Bungee until the bus came to a halt. (Of course, he then had to quickly release the Super Bungee before the bus came flying back at him.) The mass of the bus, including passengers, was 1.20×104kg , and its speed was 21.2m/s . The bus came to a stop in 50.0m. What was the spring constant of the Super Bungee? How much time after the Super Bungee was attached did it take the bus to stop?
what happens to light of a particular frequency when it is incident upon the material that natural frequency is the same as the frequency of the light.
A small ball of mass 50 g is suspended from a string of length 66-cm and whirled in a circle lying in the horizontal plane. If the string makes an angle of 21? with the vertical, find the centripetal force experienced by ball. The acceleration of ..
What vertical height does block reach above its starting point. What speed does it have when it slides back down to its starting point.
Suppose that the spring is ideal and that the distance by which the spring is compressed is negligible compared to H.
A constant horizontal force a pushes a kg FedEx package across a frictionless floor on which an xy coordinate system has been drawn. package's x and y velocity components versus time t.
You are driving to grocery store at 21. You are 100 from an intersection when the traffic light turns red. Presume that your reaction time is 0.75 and that your car brakes with constant acceleration. How far from the intersection are you when you ..
For no apparent reason, a poodle is running at a constant speed of 3.40 m/s in a circle with radius 2.8m. Let v1 be velocity vector at time t1, and let v2 be the velocity vector at time t2.
In a period of 1.0 s, 5.0 x10^23 nitrogen molecules strike a wall of area 7.80 cm2. If the molecules move at 270 m/s and strike wall head on in a perfectly elastic collision, find the pressure exerted on the wall. (The mass of one N2 molecule is 4..
The total mechanical energy of the spacecraft, assume that the gravitational potential energy is zero at an infinite distance from the Earth.
A 10 μF capacitor is charged to 15 V. It is next connected in series with an uncharged 5.00-μF capacitor. The series combination is finally connected across a 50.0-V battery, as diagrammed. Find out the new potential differences across the 5-μF an..
