A cargo plane has to drop a relief package to people in need.The plane is flying level (vertical velocity = 0) at 200 ft.The plane is traveling at a horizontal velocity of 240 ft/s in a straight line toward the drop target.
The wind resistance on the package can be neglected. When releasing the package, at what angle?(in degrees)down from the horizontal must the pilot see the target for the package to land on the target?
A solid disk rotates in the horizontal plane at an angular velocity of 0.036 rad/s with respect to an axis perpendicular to the disk at its center, what is the angular velocity of the disk
a cylinder contains 4.0moles of a monoatomic gas at an initial temp of 27deg C. How much heat flows in to our out of the gas
Assuming that all the heat generated by the resistor is absorbed by the solid substance, and that it takes 4 minutes to raise the temperature from 20to 80 degrees C, compute the specific heat for the substance.
A space traveler weighs 535 N on earth. What would the traveler weigh on another planet whose radius is three times that of earth and whose mass is twice that of earth.
Consider a single electron, with a mass of 9.1×10?31 , subject to a single force equal to the weight of a penny, What is the acceleration of the electron
What is the magnitude of an average acceleration of the ball
A heart defibrillator passes 11.0 A through a patient's torso for 5.00 ms in an attempt to restore normal beating, What was the path's resistance?
a) Write an expression for the magnitude of the force, F, that propels the dragster forward in terms of the variables provided. b) If the track has length L, select the correct symbolic equation for how fast Vf the dragster is traveling when it fi..
A rifle is aimed horizontally at a target 60 away. The bullet hits the target 2.5 below the aim point. What was the bullet's flight time
Two 1.5cm -diameter disks face each other, 2.0mm apar, What launch speed must the proton have to just barely reach the positive disk
A flight attendant pulls her 70.10 N flight bag a distance of 258 m along a level airport floor at a constant speed. The force she exerts is 36.30 N at an angle of 52.0° above the horizontal.
A projectile is launched perpendicularly upward from a planet of mass M; and radius R; its initial speed is twice the escape speed. Derive an expression for its speed as a function of the distance from the center of the planet.
