if you stand on a bathroom scale, the spring inside the scale compresses .50 mm, and it tells you your weight is 700 N. Now if you jump on the scale from a height of 1.4 m, what does the scale read at this peak.
i found an equation to use, i just can't figure out what I'm solving for. I'm...
thanks so much!
i was also stuck on this problem if you can help me.
A car at the Indianapolis-500 accelerates uniformly from the pit area, going from rest to 300 km/h in a semicircular arc with a radius of 200 m.
Determine the tangential acceleration of the car when it is halfway...
Calculate the force of gravity on a spacecraft 6400 km (1 Earth radii) above the Earth's surface if its mass is 1400 kg.
i started by using the Fg = GMm/d
and i plugged in the numbers so it looked like this
(6.67*10^-11)(1400)(?)/12800
i don't know what m should equal and i can't...
i kind of understand what you did but its not the answer. I'm using the webassign program that let's you check your homework and i tried that answer and it didn't turn out right.
i've been trying to figure this question out for about half an hour now and I'm still where I started. if some one could help me i'd be much obliged.
