Ekaferini stefandi of greece won the women's pole vault at the 2016 games in rio with a vault height of 4.85 m. we are going to calculate how fast she needed to be going to clear the bar. assuming energy is conserved. first, we must calculate this from her center of mass which is probably a meter off the ground. so her height was actually 3.85 m. calculate her speed when she planted her pole for the jump.

The of a machine determines its "usefulness." a. input force b. output force c. mechanical advantage

Both speed and velocity measure how fast something is moving. however, since speed is not a it does not require a(n question 6 options: a) quantity , unit b) magnitude, unit c) scalar, direction d) vector, direction

On a hot saturday morning while people are working inside, the air conditioner keeps the temperature inside the building at 22degreesc. at noon the air conditioner is turned off, and the people go home. the temperature outside is a constant 33degreesc for the rest of the afternoon. if the time constant for the building is 4 hr, what will be the temperature inside the building at 4 : 00 font size decreased by 2 upper p . font size decreased by 2 upper m .? at 6 : 00 font size decreased by 2 upper p . font size decreased by 2 upper m .? when will the temperature inside the building reach 24degreesc? 324281
