LOL - I have a friend who climbs towers to work on broadcast antenna systems. Here is a pic he took while at the top of one:
Personally, I think he's insane.

My inlaws went on a helicopter tour of the canyon in June . They said there was a car at the bottom of the canyon that was from a movie . I couldn’t believe it either . I figured that is the only car that went over the rim .
Not so good. he was travelling horizontally at 45 mph, theoretically. Adjusting for drag he was probably doing 40 when he hit. But he started at the top at 0 vertically, and accelerated at 32 feet per second, per second.
His horizontal travel beyond the edge of the cliff would have been ~44 feet; within the first .4 secs the vehicle would have turned nose down and its initial rate of speed would have increased from ~61 fps to roughly 188 fps at impact; time of fall would be ~6.1 secs as previously said.
No. He should get a A for his self esteem even though he had a wrong answer.
It’s not a matter of velocity, it’s a matter of how the Sparrow can grasp the coconut in the first place.....
Ok, smarty pants. Assuming the front wheels starting falling before the rear, what was the rotation rate about the pitch axis and what was his pitch angle at impact?
The acceleration from gravity is 32ft/second^2. If you drop a bullet, it’s velocity will increase at 32ft/second per each second. This is true for any object until air resistance starts to come into play.
If you shoot a round straight down it’s initial velocity will be so high, say 1500 feet/second. After one second, its velocity would have increased to 1532 feet/second, assuming zero air resistance.
A bullet fired downward is a totally different story. Think things through before you ask questions, most of the time you can figure it out.
OMG - i think i have to go lie on the ground now....
LOL
If you shoot it parallel to the bottom of the canyon it will fall at 32 feet/ sec. squared . If you shoot it toward the bottom it will travel at muzzle velocity to the bottom .
No. If you shoot the pistol towards the bottom, then the initial vertical velocity of the bullet is not zero. However, it will accelerate at (1/2)*(32 ft/sec^2) due to gravity.
v(t) = (1/2)at^2 + vt
When driving a car off the edge, there is very little initial vertical velocity (depends on the angle of the ground with respect to the drop-off). Assuming the ground is at a 90-degree angle with the drop-off, there will be no initial vertical velocity (v(0) = 0).
Looks like he's climbing a fairly rusty tower!!
I felt safer jumping out of an airplane...a few weeks ago.
Poor guy. Here he thought “I’m a failure, I’m a nobody, nobody cares for me. Well - I’ll show them. I’ll go out in a blaze of glory and drive off the edge of the Grand Canyon. They’ll ALL know my name then!! Harvey Finklebean - he drove off the edge RIGHT here!”
Instead he becomes a physics example.
I have an FCC license, I used to do all types of work on radios etc, but I would always refuse to do what your friend does. Cost me some bucks but, hey, I never fell off a tower!:)
Ever drive the Going To The Sun road in Glacier National Park? Now that's an experience you won't forget. I was driving, and at one point I asked my wife what was off to the right of my view (couldn't take my eyes off the road). She said she didn't know because she was too scared to look over the side which was about four or five thousand feet down.
“The 40 MPH quits as soon as the wheels leave the ground and gravity takes over! “
Not exactly, forward speed will affect the trajectory, but not how quickly he hits the bottom of the canyon. So if his forward speed is sufficient, and the other side low enough he could make it to the other side.
That was the basis for Eviel Kneivel’s stunt, but he may have added elevation (a ramp) to his formula.
Only for those in the private sector...
Those in government continue to receive generous wages, lottery style retirement pensions, top self medical benefits, great job security, since the government at all levels literally refuses to cut back or reduce it size.
We now work for our "public servants" and their security.
“Instead he becomes a physics example.”
Your comment cracked me up. If I were not a manly man, I would have written “LOL.”
