Document Summary
Solve the following problems in the space provided. Use the back of the page if needed. You must show your work in a logical fashion starting with the correctly applied physical principles. The equations you need are on the equation sheet. The motion sensor plots the velocity as a function of time as shown in the graph at the right. Using the definition of velocity, v " dx dt. , the distance traveled must be the area under the. 2 (2. 0)(1. 0) $ "x # 1. 0m . velocity vs. time curve. Using the definition of acceleration, a " dv dt curve. a " , the acceleration must be the slope of the velocity vs. time (d)describe the motion of the cart travel after the push is complete. The velocity slows gently as the cart continues to move away from the sensor. The slight deceleration is probably due to friction. Spring 2006: a cruise ship is 200km away from houston at.
