Assume a motion sensor is placed at the origin {i.e. position
(x) = 0}. In each of the following problems, you will be given one
of the following descriptions of motion: a written description, or
a x versus t, a
v versus t or
an a versus t
graph. Fill in/sketch the other threee descriptions of motion that
would be consistant with the given one. Don't bother with exact
numerical values, but make sure that
(a) the sign (+/-) and...

10. Move the Motion Sensor. Place the Motion Sensor at the bottom of the track pointing up the track. 11. Check the Motion Sensor. Start with the cart at least 50 em in front of the sensor. Practice pushing the cart up the track so the cart doesn't go over the top of the track and stopping the cart before it gets within the 50 em of the sensor. Start the sensor and push the carit up the track. Stop...

A student measures the velocity of an object moving along a track. At time t = 0 s, the object is moving at a constant 4.0 m/s in the positive x-direction. At time t = 3.0 s, the object begins to slow, stops at t = 5.0 s, and then moves in the opposite direction. At t = 6.0 s, the object as reached a speed of -2.0 m/s. It moves at this speed until the student quits taking data...

Problem 9 For the following described motion, draw a position-time, a velocity-time, and an acceleration-time graph on the grids provided: 1. Standing still at the 0.6 meter position for 1 second. 2. Walking away from the detector speeding up slowly and steadily for 2 seconds, going from rest to 1.0 m/s, at x=1.6 m. 3. Walking away from the detector steadily at 1.0 m/s for 2 seconds. 4. Coming to rest slowly and steadily over a 1 second period. 5....

A cat is walking along a hallway moving away from a sleeping dog. A graph of the distance between the cat and the dog as a function of time is shown to the right. A physics student uses 2) Distance, meters 20 the equation "rate times time equals distance" to calculate the speed of the cat at time 6 seconds: 16 12 distance / time 16.0 m/6s=2,667 m/s. rate 8 4 (a) What, if anything, is wrong with this calculation?...

er At time t2 23.1 s, what is the x-component of the dog's velocity? Express your answer using two significant figures. Constants A dog running in an open field has components of velocity v - 2.6 m/s and vy 1.2 m/s at time ti 10.9 s . For the time interval from t1 = 10.9 s to t2 23.1 s, the average acceleration of the dog has magnitude 0.45 m/s and direction 32.0° measured from the +z-axis toward the +y...
