A particle of mass m strikes a wall at an angle θ with respect to the normal. The collision is inelastic with coefficient of restitution E. Find the rebound angle of the particle after collision with the wall.
Assume a spacecraft is orbiting the earth at a constant radius of 7.00x10^3km. At t=0 a lateral rocket is fired that imparts an inward-directed radial velocity. What is the minimum radial velocity needed to produce a parabolic trajectory, and what wi..
It is important for the body to have mechanisms to effectively cool itself; if not, by how much would his body temperature rise during this exercise
If the x- and y-axes both carry a linear charge density of 3 nC/m, what is the electric flux through a spherical surface of radius 10 cm centered at the origin
A ball of mass 0.65 kg is fired with velocity 120 m/s into the barrel of a spring gun of mass 2.4 kg initially at rest on a frictionless surface. What fraction of the ball's initial kinetic energy is stored in the spring
A rocket for use in deep space is to be capable of boosting a total load (payload plus the rocket frame and engine) of 3.15 metric tons to a speed of 10 000 m/s. How much fuel plus oxidizer is required
Three moles of an ideal monatomic gas expands at a constant pressure of 2.90atm ; the volume of the gas changes from 3.00×10?2m3 to 4.40×10?2m3. Calculate the amount of work the gas does in expanding

When a 60 N stone is attached to a spring scale and is submerged in water, the spring scale reads 35 N. What is the density of the stone
A 54-kg water skier is being pulled by a nylon (Young's modulus 3.7 x 109 N/m2) tow rope that is attached to a boat. What is the change in length of the rope when the skier has an acceleration whose magnitude is 0.59 m/s2
A plano convex lens is placed convex side down on a plane glass plate and illuminated from the above with red loght of wavelength of 625nm. what are the curvature and focal length of the convex surface of the lens
A cloud mass moving across the ocean at an altitude of 2000 m encounters a coastal mountain range. As it rises to a height of 3500 m to pass over the mountains, it undergoes an adiabatic expansion.
Scientists want to place a 3400.0 kg satellite in orbit around Mars. They plan to have the satellite orbit a distance equal to 2.4 times the radius of Mars above the surface of the planet. Here is some information that will help solve this problem..
