- nRamps Handout 511.3: Centripetal Acceleration and Problem Solving or the diagram below you are looking down from above at a puck sliding on a frictionless abletop. The puck is sliding at a constant speed along a circular fence and just leaves ontact with the fence at position B. The fence and puck are also frictionless. a) On the top drawing draw vectors and label them for any forces acting parallel to the table top on the puck at positions A and B. b) On the side views below, draw vectors and label them for any forces acting perpendicular to the tabletop. side view at A c) Which of the forces above are inward forces? __ d) Which of the forces above are outward forces? __ e) What would be the equation for the net force on the puck? __ f) On the top drawing at position B draw a line at an inch long showing the path the puck will tr after point B. How do you know? __ g) On the bottom drawing, draw and label a and an acceleration vector on the puck a A and B. h) At position A is the net force on the pu How do you know? __
- 2. A water wave is moving outwards with a frequency of 1 wave every 10 seconds. If the wave has a velocity of 50.0cm/s and the water bug is traveling left at a speed of 20.0 cm/s , what is the wave frequency as the bug: a. Gets closer to you? b. Gets further from you?
- Momentum 1. Momentum is a quantity defined as the product of an object's __ and its __
- E.g. An intubated patient is transported to ICU using an ambubag ventilating at a rate of 10liter/min from an E type cylinder showing pressure of 800 PSI. How long (in mints)will you have before your E cylinder of oxygen runs empty?Hint; the initial filling pressure is 1900 PSI and volume of the cylinder when it is full is 660 liters.
- 5. Ared clav not was fired in a kiln to a temperatures of 2,192^circ F the kiln was then turned off and the clay pot allowed to cool slowly to a room temperature of 72^circ F before removing the pot from the kiln and painting it.It cools at a rate of 15% per hour.
