A pole-vaulter approaches the takeoff point at a speed of 6.00 m/s. Assuming that only this speed determines the height to which he can rise, find the maximum height at which the vaulter can clear the bar.
in this 1 I am lost......
I ONLUY GOT 1 GIVINGS (6.00 m/s )
should i use the ...h0-hf = m ??
person is making homemade ice cream. She exerts a force of magnitude 19 N on the free end of the crank handle, and this end moves in a circular path of radius 0.32 m. The force is always applied parallel to the motion of the handle. If the handle is turned once every 1.9 s, what is the average power being expended?
i know that the P= WORK/TIME...
AND P= CHANGE IN ENERGY/ TIME
I TRIDE BOTH ..BUT NONE OF THEM WORKED FOR ME...
