The catapults on the USS George H.W. Bush can launch aircraft from rest to a speed of 150 mph over a distance of 270 feet. Find the acceleration of the aircraft and express it in multiples of g, free fall acceleration.
A piece of string 5.30 m long has a mass of 14 g. What must the tension in the string be to make the wavelength of a 128 Hz wave 120 cm.
the earth completes a circular orbit around the sun in one year. the orbit has a radius of 93,000,000 miles. what is the speed of the earth around the sun in m/s? Report your result using scientific notation.
What mass (in grams) of steam at 100°C should be mixed with 212 g of ice at its melting point, in a thermally insulated container, to produce liquid water at 14.0°C? The specific heat of water is 4186 J/kg·K. The latent heat of fusion is 333 kJ/kg..
Two horizontal curves on a bobsled run at the similar angle, but one has twice the radius of the other. The safe speed (no friction needed to stay on the run) for the smaller radius to curve is v. What is the safe speed on the larger radius curve.
The 1 kg block is tied to the wall with a rope. It sits on top of the 2 kg block. The lower block is pulled to the right with a tension force of 20 N. The coefficient of kinetic friction at both the lower and upper surfaces of the 2kg block is = 0..
An asteroid is discovered heading straight toward Earth at 13km/s. An international team manages to attach a giant rocket engine to the asteroid. The rocket fires for 10 mins, after which the asteroid is moving at 28 degrees to its original path at a..
Calculate the horizontal force that must be applied to a 1.00 kg puck to make it accelerate on a horizontal friction-free air table with same acceleration it would have if it were dropped and fell freely.
A projectile is fired at an upward angle of 45° from the top of a 308m cliff with a speed of 198 m/s. What will be its speed while it strikes the ground below? (Use conservation of energy.)
A helicopter is ascending vertically with a speed of 5.02m/s. At a height of 140m above the Earth, a package is dropped from the window. How much time does it take for the package to reach ground.
A total electric charge of 4.50 nC is distributed uniformly over the surface of a metal sphere with a radius of 22 cm. The potential is zero at a point at infinity. Find the value of the potential at 45 cm from the center of the sphere.
A golf ball strikes a hard, smooth floor at an angle of 30 ° and, as the drawing shows, rebounds at the same angle. The mass of the ball is 0.047 kg, its speed is 45 m/s just before and after striking the floor. What is the magnitude of the impuls..
A 2.50g ice flake is free from the edge of a hemispherical bowl whose radius r is 31 cm. The flake-bowl contact is frictionless. What is the speed of the flake when it reaches the bottom of the bowl?
