How would longer stops affect his average velocity?
The average velocity=(u+v)/2 where u is the initial velocity and v is the final velocity, in this case zero.
Therefore average velocity=u/2.
Since average velocity depends only on the initial velocity longer or shorter stops do not affect it.
Bob drives his car 119 km [N], then he stops to get gas. Then he drives his car 169 km [E], and stops to eat doughnuts. The he drives his car 279 km [S], and his journey ends. Bob's trip is completed in a time of 9.61 hours. The mass of his car is 1617 kg. What is the magnitude of Bob's average velocity in km/h and the direction?
A bear runs at John with a velocity of 12m/s. John stops the bear by pushing on it for 2 seconds in a motion opposing the bear’s. If the bear weighs 200kg, what average force is needed to stop the bear? Answer: -1200N The answer is given, but I would like to know how to do this problem.
When FDR closed the banks during his declared "banking holiday" how would it affect the aggreagte demand?
Page |2 3. A marathoner runs due east for 61.5% of the time, stops and rests for 6.5% of the time, and then runs due west for remainder of the time. The average eastward velocity has magnitude 12.5 miles/hour while the average westward velocity has a magnitude of 11.0 miles per hour. Find (a) the average speed, and (b) the average velocity for the entire race. (c) How far did he run for a total time 2 hours 20 min...
From his house, Jack bikes at a constant velocity of 8.5 m/s {east} for 40 seconds. He suddenly stops and takes a 10 second break. Then he heads south at a constant acceleration of 1.3 m/s/s {south} for 7.0 seconds. Determine his average velocity for the entire trip
v-O [al b) A driver engages in a collision with a wall, where his car stops moving [See Diagram a]. In a different collision, a driver collides with another vehicle, and his car stops moving [See Diagram b]. Assuming the mass of the cars is the same, and the initial velocity before each collision is the same, compare the change in momentum of the left-hand car in collision (a) to the left-hand car in collision (b). 2. 3. In a...
How would a downward change in the money supply affect you personally? How would it affect your career? What impact would rational expectations have on your decisions in this situation?
A bus travels 280 km south along a straight path with an average velocity of 88 km/h to the south. The bus stops for 24 min, then it travels 210 km south with an average of 75 km/h to the south.a. How long does the total trip last?b. What is the average velocity for the total trip?
Bill laid on his back sunbathing. Describe how his body posture/position affect his respiration in terms of (1) abdominal breathing (2) lung volume and (3) inspiration. What forces are involved in passive expiration?
When Matt turned 25 he invested $2,500 in his retirement account for 10 years and stops. He earns an 8% return. Clay invests $2,500 from age 36-65 (30 years) and stops. He earns the same 8% return. How much money will each of then have at age 65? Who has more money and by how much?
