When walking straight West, which number would change on the GPS unit,
the N 06° 54.540'or the E 158° 09.650' number?
_________ _____ The classroom is at E 158° 09.651'. Binky was at E 158° 09.519'. Use a value of 1874 meters per minute to calculate the distance from the classroom to Binky.
____________________ Plot the data in table two on the graph. Calculate the slope of the line.
Volume V = length l × width w × height h
mass m = density ρ × Volume V
distance d = velocity ѵ × time t
ѵ = at
d = ½at² d = ½gt²
Gravitational Potential Energy = mgh Kinetic Energy = ½mѵ²
momentum = mѵ
Force F = mass m × acceleration a
where: a is acceleration d is distance Δ is "the change in" (greek lowercase delta)
g is the acceleration of gravity where g is: g = 980 cm/s² (cgs) g = 9.8 m/s² (mks)
