The catapult on an aircraft carrier can take an aircraft from 0 to 182 mph in 11 seconds, at which time the aircraft launches. Express the launch speed in SI units (meter-kilogram-second system - not km/hr).
A 66.5kg astronaut is doing a repair in space on the orbiting space station. She throws a 2.30kg tool away from her at 3.10m/s relative to the space station, With what speed will she begin to move
Order of magnitude estimation: Using physics intuition, estimate the muzzle velocity of a projectile launcher
A photoflash unit makes a very bright light for a very short time, Which is important: the intensity of the light, or the product of the intensity and the time of the flash
carnival ride has a large horizontal steel disc of radius 5m from which cars are suspended by a 6m long chain. the disx is rotated about its axis so that the cars swing out and revolve in a circular path. at operation speed the angle of the chains ..
A narrow beam of light with wavelengths from 450 nm to 700 nm is incident perpendicular to one face of a 32.00, What is the angular spread of the beam after passing through the prism
An 80 g, 35 cm long rod hangs vertically on a frictionless, horizontal axle passing through its center. A 13 g ball of clay travelling horizontally at 2.50 m/s hits and sticks to the very bottom tip of the rod.
a block on a frictionless horizontal surface is attached to a spring (k=30 N/m). the mass is displaced to the right of equilibrium and released from rest. calculate amplitude of oscillations
If the mass of a sliding block is tripled at the equal time the net on it is tripled, how does the resulting acceleration compare with original acceleration?
20 g of helium are placed in a cylinder with a movable piston. What is the maximum temperature reached during the compression
What is the car's maximum speed on an incline of 1 in 20 (ie, if theta is the angle of the incline with the horizontal, sin = 1/20)? Illustrate what is its power output on a 1-in-10 incline if the car is traveling at 10 m/s?
A 3 kg block is observed to accelerate at a rate twice that of the 6 kg block. Is the net force acting on the 3 kg block therefore twice as large as that performing on the 6 kg block? Explain.
