Two objects of masses m and 3m are moving toward each other along the x-axis with same initial speed v0. The object with mass m is traveling to the left, and the object with mass 3m is traveling to the right. They undergo an elastic glancing collision such that m is moving downward after the collision at right angles from its initial direction.
(a) Find the final speeds of the two objects.
(b) What is the angle at which the object with mass 3m is scattered?
Conclude the magnitude of angular acceleration
A spring with a spring constant k of 18 N/m is stretched a distance of 12 cm (0.12 m) from its original unstretched position. What is the increase in potential energy of the spring?
A humanitarian aid package is dropped from a plane flying horizontally 500m above the ground with a speed 100m/s. What is the speed of the package at time of impact? (Calculate the total speed, not a horizontal or vertical projection.)
Find out the altitude of the plane
Two point charges of equal magnitude are 7.3cm apart. At the midpoint of the line connecting them, their combined electric field has a magnitude of 40N/C . Find the magnitude of the charges.
A thin, light wire is wrapped around the rim of a wheel. The wheel rotates without friction about a stationary horizontal axis that passes through the center of the wheel. The wheel is a uniform disk with radius 0.28. An object of mass 4.0 is suspend..
what is the needed magnitude of the minimum acceleration.
While the dried up seed pod of a scotch broom plant bursts open, it shoots out a seed with an initial velocity of 2.4 m/s at an angle of 60° above the horizontal.
A surface is infinitesimally close to and surrounds a dipole. The electric flux during the surface must be zero, since the net charge it surrounds is zero. How is it possible for the dipole to have an electric field and be consistent with Gauss' t..
The position of a cart that is oscillating on a spring is given by the equation x= 12.3 cm cos [(1.26 s-1)t] . When t= .805s , what are the (a) velocity and (b) acceleration of the cart ?
What is the electric potential energy of the system? (Take as zero the potential energy of the three charges when they are infinitely far apart.)" Use = 8.85 10 12 for the permittivity of free space.
A thin metallic spherical shell of radius 41.6 cm has a total charge of 8.05 ?C uniformly distributed on it. At the center of the shell is placed a point charge of 2.83 C. What is the electric field at a distance of 23.9 cm from the center of the ..
