A projectile is launched on the Earth with a certain initial velocity and moves without air resistance. Another projectile is launched with the same initial velocity on the Moon, where the acceleration due to gravity is 1/6 as large.
Calculate the frictional force needed for a 900 kg car traveling around a 500 m radius curve at 25 m/s, if the car is to continue moving in a circle and not slide. Assume an unbanked curve.
Calcultae the strength of the smallest electric field, to be set up over same region, that will allow the proton to pass through undeflected. a) First find the speed of the proton at the end of the accelerating potential differnce.
(a) If the collision is perfectly inelastic, calculate the speed and direction of the players just after the tackle. (b) Determine the energy lost as a result of the collision.
In the sum A + B = C, vector A has a magnitude of 11.0 m and is angled 33.5° counterclockwise from the +x direction, and vector C has a magnitude of 15.0 m and is angled 21.5° counterclockwise from the -x direction. What are the magnitude
The average density of the planet Uranus is 1.27*103kg/m3. The ratio of the mass of Neptune to that of Uranus is 1.19. The ratio of the radius of Neptune to that of Uranus is 0.969. Find the average density of Neptune.
A beam of red light of wavelength 700 nm shines on a single slit of width 122um. The light falls on a screen 0.8 meters away. Sketch the resulting interference pattern, and show the separation between bright and dark bands on the screen.
Rank the periods of the following oscillating systems from greatest to smallest. If any periods are equal, show their equality in your ranking. (Use only ">" or "=" symbols. Do not include any parentheses around the letters or symbols.)
Two protons are placed at a = 5.05 cm above and below the x axis at x = 0 as shown in the figure. An electron is placed along the x axis a distance b = 11.7 cm from the origin. a) Determine the magnitude of the electrostatic force on the electron.
If the radius of the equipotential surface of a point charge is 23.0m and is at a potential of +1.30kV (compared to zero at infinity), what are the magnitude and sign of the point charge?
