A projectile is shot on level ground with a horizontal velocity of 18 m/s and a vertical velocity of 41 m/s.
1. Find the time the projectile is in the air. The acceleration due to gravity is 9.8 m/s2.
2. Find the range
3. Find the height attained for the maximum range.
What is new angular speed of the merry-go-round
A wall in a house contains a single window. The window consists of a single pane of glass whose area is 0.11 m2 and whose thickness is 8 mm. Treat the wall as a slab of the insulating material Styrofoam whose area and thickness are 15 m2 and 0.10 ..
A spherical shell has an outside radius of 2.6cm and an inside radius of a. The shell wall has uniform thickness and is made of a material with density 4.70g/ cm3. The space inside the shell is filled with a liquid having a density of 1.23g/cm3.
A contact lens is made of plastic with an index of refraction of 1.36. The lens has an outer radius of curvature of +1.91 cm and an inner radius of curvature of +2.41 cm. What is the focal length of lens?
The inner surface is negative relative to the outer surface. Explain how much work is required to eject a positive sodium ion (Na+) from the interior of the cell?
The radius of the circular orbit is 8.92 × 106 m. Examine the magnitude of the gravitational force exerted on the satellite by the planet.
What is the average force exerted on the ball. How fast (in ) must a centrifuge rotate if a particle 6.50 from the axis of rotation is to experience an acceleration of 125,000 's.
The lighter ball is pulled away to a 60 degrees circular angle with the vertical and released. Illustrate what is the speed of the lighter ball before impact?
The astronaut pushes on the satellite, giving it a speed of 0.25 directly away from the shuttle. Seven-and-a-half seconds later the astronaut comes into contact with shuttle.
A 140 kg piano is being lifted at a steady speed from ground level straight up to an apartment 16.0 m above the ground. The crane that is doing the lifting produces a steady power of 400W. Explain how much time does it take to lift the piano?
A shotgun fires a large number of pellets upward, with some pellets traveling very nearly vertically and others as much as 1.0o from the vertical. suppose that the initial speed of the pellets is uniformly 150ms-1 and ignore air resistance.
