Calculations

Givens:

t = 4 minutes = 240 seconds

d = 240 m

v = d/t

v = 240 m/240 s

v = 1 m/s

Givens:

t = 15 minutes = 900 sec

d = 1.4 miles = 2.25 km

v = d/t

v = 2.25 km/900 sec

v = 0.0025 km/sec

v = 2.5 m/s

Givens:

t= 3 minutes = 180 sec

Θ = 6 revolutions = 12π

w = Θ/t

w = 12π/180 sec

w = 0.20943951 radians/sec

w = 0.21 radians/sec

Givens:

g = 9.81 m/s^2

h = 200 ft = 60.96 m

PE = KE

mgh = (1/2)mv^2

gh = (1/2)v^2

2gh = v^2

2(9.81 m/s^2)(60.96 m) = v^2

1196.0352 m^2/s^2 = v^2

v = 34.58 m/s
