PHYSICS 2204UNIT 2: DYNAMICS Section 2.3 – Momentum and Impulse The Physics of Sliding
The Physics of Sliding On Saturday afternoon I decided to conduct a little physics experiment that relates to our studies on momentum and impulse. Materials required for this experiment: • 1 Plastic Saucer from Canadian Tire: $4 • Nerves of Steel: Priceless Let’s check out the video...
The Physics of Sliding Our given information: • Mr. Hearn’s mass is 70 kg • The hill is 350 m long • It took Mr. Hearn 18 s to complete the run
The Physics of Sliding Find Mr. Hearn’s velocity. Convert this to km/h for our reference and comparison.
The Physics of Sliding Calculate Mr. Hearn’s momentum as he travels down the hill. Calculate Mr. Hearn’s momentum when he is stopped in the snow bank.
The Physics of Sliding What is Mr. Hearn’s change in momentum? As you can see at the end, Mr. Hearn crashes into a snow bank. What was the impulse of this collision?
The Physics of Sliding If the collision time was 0.9 s, what was the impact force exerted on Mr. Hearn when he crashed into the snow bank?
The Physics of Sliding Who said physics couldn’t be fun? Please do not attempt this experiment without a parent or guardian’s consent
