In the last seconds of the championship basketball game, a 7 ft center's team is down by 2 points. He must make a 3 point shot to win the game. He is standing on the 3 point shot line, 7.24 meters from the center axis of the basket, which is 3.05 m above the floor of the gym. His jump shot originates level with the basket and he shoots the ball with an initial velocity of 10 m/s. Find the highest trajectory that the ball can travel to land in the middle of the basket without hitting the backboard.
The distance between the first and fifth minimum on a screen 60 cm behind the slits is 6.0 mm. What is the wavelength of the light used in this experiment.
To transmit only portions of an input wave lying on one side of an amplitude boundary, you would use a.
An unstretched spring has a length of 0.30 m. while the spring is stretched to a total length of 0.60 m, it supports traveling waves moving at 4.5 m/s. How fast would waves travel on this spring if it is stretched to 0.90 m.
A person pulls on a 50kg desk with a 200 N force acting at a 30 degree angle above the horizontal. The desk does not budge.
The first person is initially moving forward with a speed of 2.5m/s and second person is initially at rest. What are the velocities of the two people after the snowball is swapped? Disregard friction between the skate and the ice.
parachutist with a camera, both descending at a speed of 13 m/s, releases that camera at an altitude of 110-m.
A spaceship moves past you at speed v. You calculate the ship to be 364 m long, whereas an astronaut on the ship measures a length of 420 m. Find v.
Assume we have an infinitely long wire carrying a current of 2-A. It is bent into an L-shape extending into positive infinities along the x- and y- axes. Find out the magnitude of the magnetic field at a point P with coordinates (0.3 m, 0.3 m).
The work on a system with a mass 100 lbm is known to be 10 BTU's . If there is no change in potential energy and the speed changes from rest to 32 ft/sec. What is the change in the internal energy of the system?
An object falls because of gravity at a rate of -9.80 m/s2 (- sign is indicative of a downward direction) for 10.00 Seconds. If it starts from rest (vo= 0) and its position starts from do= 0.0, where is it 10.00 Seconds later.
When two tuning forks of 128 Hz and 149 Hz, respectively, are sounded simultaneously, how various beats per second are heard.
Recognize and sketch all the external forces acting on the chair. Because the chair can be represented as a point particle of mass, draw the forces with their tails centered on the black dot in the middle of chair. Be certain to draw the forces so th..
