Joey is walking at a constant speed to his truck and quickly realizes that he forgot his wallet. He runs back to the house to retrieve his wallet. His motion could be described as having: Please explain your answer choice.
A. negative velocity toward the car and positive acceleration back to the house.
B. positive velocity toward the car and negative velocity back to the house.
C. positive acceleration toward the car and negative acceleration back to the house.
D. positive acceleration toward the car and negative speed back to the house.
Homework Answers
Solution:
(A)
Negative velocity toward the car and positive acceleration back to the house.
He kept moving in towards his car after getting his wallet => negative velocity
& as he runs back to the house => increase in the velocity => positive acceleration.

________ In many cartoon shows, a character runs off a cliff, realizes his predicament, and lets out a scream. He continues to scream as he falls. If the physical situation is portrayed correctly, from the vantage point of an observer at the top of the cliff leaning over the edge, the pitch of the scream as he falls should be A) higher than the original pitch and constant. B) higher than the original pitch and increasing as he falls. C)...

1. A car traveling at a speed of vo = 52 m/s stops smoothly (that is, its deceleration is constant) over a distance of d = 147 m. After the car has gone 1/3 of the stopping distance, what is its speed? v1/3 = 2. An athlete sprinter 50m in 9.3 seconds, and then walks slowly back to the starting line in total time of 58 seconds. (Assume he runs in the positive direction.) What is his average walking velocity? vav...

Rush Inuit is an impulsive, fly-by-the-seat-of-his-pants kind of guy. His best friend, Stu Earley, is the exact opposite – cautious and reluctant. The two are recent UNCG graduates who roomed together all … ahem … eight years. You know who they are even though they graduated last year because everyone on campus knows Rush and Stu – they’re legends on the social scene. To make ends meet during college, Rush and Stu organized fun trips to exciting destinations and charged...

Except for a few pigeons, Central Park was deserted
Except for a few pigeons, Central Park was deserted. Mist hung above the chilled grass. Patches of old snow, scattered here and there, looked like white puddles. The sun hung just above the horizon, casting red and orange streaks across low-hanging clouds. The portly, gray-haired gentleman jogging down the path looked out of place. For one thing, he was dressed in ordinary street clothes, not a sweat suit. Also, every few seconds, he looked anxiously back over his shoulder. Coming...
