how do we solve it????-two transmitters on land At fixed know locations so you know the distance between the two transmitters And from the signals you know the distance between the ship and both tran

What is called electro magnet

A current carrying coil of insulated wires wrapped around a piece of iron is called electro magnet-Hi friend Karthikha Rani, there are two magnets basically. One is permanent and the other one is temp

At an instant when a soccer ball is in contact with the foot of a player kicking it, the horizontal or x component of the balls acceleration is 765 m/s2 and the vertical or y component of its accelera

A highway curve of radius 420 m is designed for traffic moving at a speed of 91.0 km/hr.

What is the correct banking angle of the road?-V = 91/3.6 = 25.27 m/s Θ = arctan[V²/Rg] = arctan[25.27²/(420*9.8)] = 8.82°

What is the difference between average velocity and constant velocity

Average velocity is an objects total displacement divided by the time it took to make that displacement. Constant velocity means an object is traveling in a straight line with the same speed.If an ob

Physics problem. Force and Motion.

A passenger with mass 85 kg rides in a Ferris wheel. The seats travel in a circle of radius 35 m. The Ferris wheel rotates at constant speed and makes one complete revolution every 25 s. Calculate the

Physics- Inclined Planes w/Friction Help?!

Q: A Chevrolet Corvette convertible can brake to a stop from a speed of 60.0 mi/h in a distance of 123 ft on a level roadway. What is its stopping distance on a roadway sloping downward at an angle of

Please solve this problem

A machine project an object of mass 0.2 kg from some hight with initial speed of 3m/s. Find the work done by machine on object. Is it positive or negative please explain.-Hmm.. [0.2kg]: initial spee

Static equalibrium problem

An accident victim with a broken leg is being placed in traction. The patient wears a special boot with a pulley attached to the sole. The foot and the boot together have a mass of 4.0 kg , and the do

What force is required to lift a 9kg object at a constant speed of 2 m/s

How do I find the force required to lift a 9kg object at a constant speed of 2 m/s?-The speed does not matter once you get the object to any constant speed F = MA = 9kg * 9.8 m/s^2 =-Force = (9 x 9.8

Physics help please :)

Heather and Matthew walk eastward with a speed of 0.92 m/s east. If it takes them 34 min to walk to the store, how far have they walked? Answer in units of km-They move at 0.92 m/s. To work with this

Acceleration of a rocket taking off.

Suppose the mass of a fully loaded module in which astronauts take off from the moon is 10,000 kg. The thrust of its engines is 30,000 N. Calculate its acceleration in a vertical takeoff from the moo

Calculate RPM with acceleration and radius

How fast (in rpm ) must a centrifuge rotate if a particle 8.50cmfrom the axis of rotation is to experience an acceleration of 125,000gs?-centrip accel = v^2/r 1 g = 9.8m/s/s so this acceleration = 1.

If a rocket's vertical acceleration is 9.8 m/s...

and the initial velocity is 0, would the rocket move at all? Or would gravity affect the rocket, and make it stay in place?-Yes, it would accelerate upwards at 9.8 m/s^2.The upward acceleration alread
