Q20. An object is shot straight up from 10 m above ground level with an initial velocity of vo = 17 m/s. After how many seconds will it return to the ground if the effects of the air are neglected? Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point. Take g=9.81 m/s². Your Answer: Answer

According to Timothy Treadwell in 2001 "Now, the bears I live with average, the males are on average twelve hundred pounds. They're the largest bears in the world and they've been clocked at 41 [mph] and they've run a hundred meter dash in 5.85 seconds which human on stimulants doesn't even approach. a. Compute the speed of a grizzly bear using Mr. Treadwell's hundred-meter statement. b. Compute the momentum of a grizzly bear using the speed you calculated in part a. and the average mass stated by Mr. Treadwell. c.

hat number w.ww The word "units" refers to the corresponding quantity of something. For example, 2 is a number; 2 seconds is a physical quantity that has the units of second. In physics problems, are usually not looking for a number; we are looking for a need to also know the units. If you do not include units with the answer, you will not receive physical quantity, which means we full credit. Physicists are very nitpicky about this! 8.
