Wednesday, January 13 th Agenda  Speed Worksheet  Questions/problems?/Collect  Quick review  DIGIT Quiz (Did I Get It?)  Movie: “ World’s Fastest“  Go over speed worksheet We will be doing a fun lab on Friday!

Speed Worksheet  Questions?  Problems?  Hand In

Quick Review A man drives at a speed of 55.0 mi/hr for 4.25 hours. How far did he travel?  Equation to use: Distance=Speed X Time Speed = 55.0 mi/hr Speed = 55.0 mi/hr Time = 4.25 hrs Time = 4.25 hrs Solve: Distance = (55.0 mi/hr) (4.25 hr) Solve: Distance = (55.0 mi/hr) (4.25 hr) = 234 mi = 234 mi

Quick Review You finish a m race in 1.6 min. What is your speed in m/s?  Equation to use: Speed = Distance Time Time Distance = m Distance = m Time = 1.6 min X 60 s = 96 s Time = 1.6 min X 60 s = 96 s 1 min 1 min Solve: Speed = m = 5.2 m/s Solve: Speed = m = 5.2 m/s 96 s 96 s

Quick Review A pitcher throws a baseball towards home plate, a distance of 60.5 ft. The ball reaches home plate in 0.63 s. What is the velocity of the ball?  Equation to use: Speed = Distance Time Time Distance = 60.5 ft Distance = 60.5 ft Time = 0.63 s Time = 0.63 s Solve: Speed = 60.5 ft = 96 ft/s towards 0.63 shome plate Solve: Speed = 60.5 ft = 96 ft/s towards 0.63 shome plate (Remember: Velocity has DIRECTION!)

Quick Review An Olympic athlete with a mass of 73.0 kg runs with a constant forward velocity of 1.50 m/s. What is the athlete’s momentum?  Equation to use: Momentum = Mass X Velocity Mass = 73.0 kg Mass = 73.0 kg Velocity = 1.50 m/s forward Velocity = 1.50 m/s forward Solve: Momentum=(73.0 kg)(1.50 m/s forward) Solve: Momentum=(73.0 kg)(1.50 m/s forward) = kgm/s forward = kgm/s forward

DIGIT Quiz (Did I Get It?)  You may use your book and your notes to complete the quiz… Good Luck!

Movie: “World’s Fastest“  Write down 20 things you learned from the movie…
