I am a currently a junior searching for colleges. I want to be an engineer and specialize in environmental/clean energy. My ideal job would be working for an energy company making, designing or inventing clean energy alternative technology.
What are the advantages of majoring in environmental...
Hi, I am a junior in high school starting the college process. I want to go into engineering focusing on clean energy. For example, designing windmills or fuel cell engines. My dream job would be working for a company that builds clean energy plants. What major should I pursue? Are there any...
I am currently a junior in high school taking physics A. I find it very easy and natural and have an A for 1st semester and a 97 on the midterm. I want to take AP physics but i am not sure which one. In college i am most likely going into construction so I will need a lot of math and physics...
Homework Statement
In order for a satellite to move in a stable circular orbit of radius 6736 km at a constant speed, its centripetal acceleration must be inversely proportional to the square of the radius r of the orbit.
What is the speed of the satellite? The universal gravitational constant...
Homework Statement
On takeoff” refers to after the plane has left the ground.
On takeoff, the combined action of the air around the engines and wings of an airplane exerts a(n) 8445 N force on the plane, directed upward at an angle of 50.2◦ above the hori- zontal. The plane rises with...
What is the formula for that. This is just a guess. T=A/Ff? So T=29900/1274? T=23.47s? And then i used the kinematics equation DeltaX= vf+vi/2 x t and got 350.88 m
No it doesnt i was wrong. F=mass x acceleration. Acceleration is 0 because it is a constant velocity. So wouldn't that mean that force=0 because 1000kg x 0= 0. So then wouldn't there only be force of friction?
Well i plugged in 1000kg for mass and got 9800N for normal force so Ff=1274N. Not i need to figure out what to do with Ff. If the mass is 1000kg then it is raveling with a force of 29900N (F=MV). So there is 29900N forcer going forward and a 1275.3N Force of friction. I do not know what i do...
Homework Statement
A car is traveling at 66.9 mi/h on a horizontal highway.
The acceleration of gravity is 9.8 m/s2 .
If the coefficient of friction between road and tires on a rainy day is 0.13, what is the minimum distance in which the car will stop? (1 mi = 1.609)
Answer in units of m...
