A plane weighing 220 kN (25 tons) lands on an aircraft carrier. The plane is moving horizontally at 63 m/s (141 mi/h) when its tailhook grabs hold of the arresting cables. The cables bring the plane to a stop in a distance of 89 m.
(a) How much work is done on the plane by the arresting...
oh...my work
So through using said acceleration equation
(v squared = v initial squared plus 2(acceleration)(displacement)
so i got that the acceleration is 6.05 cm/s
then from that i got that the time is equal to 22= 6.05t
So t is 3.64 seconds.
So I'm guessing there's a way to...
hey all
i have this very annoying physics problem that I've been looking at for hours.
In the physics laboratory, a glider is released from rest on a frictionless air track inclined at an angle. If the glider has gained a speed of 22.0 cm/s in traveling 40.0 cm from the starting point, what...
Look guys, this isn't homework and I am not asking anyone to do it for me. Its just in the review for a huge test (the final) tomorrow and i can't remember back to when we studied it. If someone could even just give me the equation so i could solve it myself id be most grateful.
Hum. Confused.
Two charges -4.0mC and -5.0mC are separated by a distance of 20cm. What is the electric field halfway between the charges?
Coulombe's law only tells me the force on a particle next to another one. I don't know the formula for calculating an electric field, let alone...
Woo, this is on my final exam and i don't know if there's a formula or something to solve it. really need help. anything is appreciated.
A converging lens with a focal length of 15.0 cm is placed 53 cm from a light bulb. Where would you place a screen to focus an image of the object? :rolleyes:
Hey
My midterm is tomorrow and i don't know how to do this! See if one of you does.
A 850 N person sits 1.2 m from one end of a swing (5 m long) supported at each end by a chain. The swing weighs 250 N and there is a 40 N can of soda .5 m from the end opposite the person. How much force...
