Q. An airplane has an effective wing surface area of 22.4 m2 that is generating the lift force. In level flight the air speed over the top of the wings is 55.0 m/s, while the air speed beneath the wings is 31.0 m/s. What is the weight of the plane?
Q. A 0.157 kg ball is thrown straight up from 1.94 m above the ground. Its initial vertical speed is 9.60 m/s. A short time later, it hits the ground. What is the total work done by the force of gravity during that time?
A small remote-control car with a mass of 1.60 kg moves at a constant speed of v = 14.0 m/s in a vertical circle inside the hollow metal cylinder that has the radius of 5.00 m.
If an average frequency emitted by a 200,-,rm W light bulb is 5.00 times 10^{14} , {rm Hz}, and 10.0 percent of the input power is emitted as visible light, approximately how many visible-light photons are emitted per second .
A shopper pushes a cart 39 m south down one aisle and then turns 90.0° west and moves 22 m. He then makes another 90.0° turn and moves 14 m.
A father (m = 90 kg) and son (m = 45 kg) are standing facing each other on a frozen pond. The son pushes on the father and finds himself moving backward at 3 m/s after they have separated. How fast is the father moving.
A student eats a candy bar that may give 1.8 * 10^6 joules of energy. if the student has a mass of 60 kg, how high will he have a climb a ladder to offset completely the energy contained in the candy bar.
How many 95W light bulbs can you use in a 120V circuit without tripping a 17A circuit breaker? (The bulbs are connected in parallel, which means that the potential difference across each light bulb is V.)
An airplane is flying with a velocity of 86.0 at an angle of 23.0 above the horizontal. When the plane is a distance 114 straight above a dog that is standing on level ground, a suitcase drops out of the luggage compartment.
A long solenoid has 80 turns/cm and carries current i. An electron moves within the solenoid in the circle of radius 3.10 cm perpendicular to the solenoid axis. The speed of an electron is 0.0330c (c = speed of light). Find current i.
Laser light at 635 falls on a double-slit apparatus with slit separation 6.9 .Find out the separation between the third and fourth bright fringes, as seen on a screen 1.4 from the slits.
Find the magnitude of the maximum force applied horizontally to upper block (block 1) that will cause the two blocks to slide together.
What is wind velocity
The height of a helicopter above the ground is given by h = 3.00 t3, where h is in meters and t is in seconds. After 2s, the helicopter releases a small mailbag. How long after its release does the mailbag reach the ground.
