A snowboarder hits end of jump at speed of 14.0 m/s. The boarder is traveling at 13.) mi/s at highest point of jump. Determine height at highest point in air, ignoring air resistance.
A 47.0 g golf ball is driven from the tee with an initial speed of 60.0 m/s and rises to a height of 25.2 m, Neglect air resistance and determine the kinetic energy of the ball at its highest point
A car originally at 14 m/s ( about 50 kph) covered a distance of 250 m. If its speed at the end of trip is 20 m/s ( about 72 kph), how long did it take the car to cover that distance
While Voyager 2 sent back pictures of Neptune during its historic flyby of that planet in 1989, the spacecraft's radio signals travelled for 4 hours at the speed of light to reach Earth. How far away was the spacecraft.
A beam of light in the air makes an angle of 47.5 degrees with the surface (not the normal) of a glass plate having a refractive index of 1.66. (a) what is the angle between the reflected part of the beam and the surface of the glass?
A long solenoid, with its axis along the x axis, consists of 180 turns per meter of wire that carries a steady current of 15.0 A. A coil is formed by wrapping 30 turns of thin wire around a circular frame that has a radius of 7.00 cm. The coil is ..
two forces are applied to a car in an effort to move it, as shown in the following figure, where F1 = 448 N and F2 = 350 N. What is the resultant of these two forces
A uniform electric field of magnitude 271 V/m is directed in the negative x direction. A +12.7 ?C charge moves from the origin to the point (x, y) = (15.5cm, 46.0 cm). What was the change in the potential energy of this charge?
A magnetic field is oriented at an angle 42 degrees to the normal of a rectangular aread 5.5 cm by 6.8 cm. evaluate the strength of the magnetic field
The speed of sound in bone is 3500 m/s. How much time does it take the echo of a sound wave to travel from the back of the bone to the front of the bone if the bone is 2.50 cm thick.
Starting from rest, object 1 is subject to a 10Nforce for 2.0 s. Object 2, with twice the mass, is subject to a 15N force for 3.0 s
In the amusement park ride known as Magic Mountain Superman, powerful magnets accelerate a car and its riders from rest to 38 m/s (around 90 mi/h) in a time of 7.5 s. The mass of the car and riders is 3600 kg. Find the average net force exerted on th..
