A wave on a string is described by the relation y = A sin(47t - 0.023x), where t is measured in seconds and x in meters, with A = 0.18 m
a. Find the frequency of the wave
b. Find the wavelength of the wave
c. Find the speed of the wave
The first puck is deflected 38 below the +x axis and moves off at 0.37 m/s. Find out the speed and direction of the second puck after the collision.
A 28.0 g object moving to the right at 18.0 cm/s overtakes and collides elastically with a 9.0 g object moving in the same direction at 15.0 cm/s. Find the velocity of each object after the collision
In what time interval does it reach this velocity. How high would the insect jump if air resistance were negligible.
A projectile is fired with muzzle speed 150m/s, Where does the projectile hit the ground with what speed
The potential at location A is 376V. A positively charged particle is released there from rest and arrives at location B with a speed vB.
A 10kg mass that is moving at 15m/s hits a stationary 10kg mass. The collision is elastic. what is the total momentum BEFORE the collision
An object of mass 5kg is moving with an momentum of 50 kg m/s. What is the speed of the object? What is the magnitude of the momentum of the object
A 13g bullet traveling 221 m/s penetrates a 2 kg block of wood and emerges cleanly at 160 m/s. If the block is stationary on a frictionless surface when hit, how fast does it move after the bullet emerges.
It's found that string is set into oscillation only at the frequency 880 Hz and 1320 Hz as the frequency of an oscillator is varied over the range 500-1500 Hz. What is the tension in the string.
A rock of mass 34 kg accidentally breaks loose from the edge of a cliff and falls straight down. The magnitude of the air resistance that opposes its downward motion is 248 N. Elucidate what is the magnitude of the acceleration of the rock?
A 59.00kg skier encounters a dip in the snow's surface that has a circular cross section with a radius of curvature of 12-m. If the skier's speed at point A is 7.0 m/s, what is the normal force exerted by the snow on the skier at point B? Ignore f..
A paperweight is made of a solid glass hemisphere with index of refraction 1.50. The radius of the circular cross section is 4 cm. The hemisphere is placed on its flat surface, with the centre directly over the 2.5 mm long line drawn on a sheet of ..
