mixer [17]

Answer: 0.04 s

Explanation:

The given equation for the period T of a pendulum when the acceleration due gravity is given in feet per squared second g=32 ft/s^{2} is:

T=2 \pi \sqrt{\frac{l}{32 ft/s^{2}}}

Where l=\frac{1}{18} ft is the length of the pendulum

T=2 \pi \sqrt{\frac{\frac{1}{18} ft}{32 ft/s^{2}}}

T=0.04 s

The 25-mph zone is 150 yards long. How much time did the student save (in seconds) by speeding past the school
VikaD [51]

Answer:

Time = 12.27seconds

Explanation:

Given

Speed = 25miles/hour

Distance = 150 yards = 150(0.000568182)miles

Distance (in miles) = 0.0852273miles

Get the time

Speed = Distance/Time

Time = Distance/Speed

Time = 0.0852273/25

Time = 0.0034hours

Time = 0.0034 * 3600secs

Time = 12.27seconds
