Now she is out on a hike and comes to the left bank of a river. there is no bridge and the right bank is 10.0 m away horizontally and 2.5 m, vertically below. if she long jumps from the edge of the left bank at 45 ∘ with the speed calculated in a, how long, or short, of the opposite bank will she land?

Asmall object with mass 0.200 kg swings back and forth on the lower end of a light rope that is 3.00 m long. the upper end of the rope is attached to the ceiling. as the object swings through its lowest position, where the rope is vertical, the speed of the object is 5.80 m/s. at this point in the motion, what is the tension in the rope? (use g = 9.80 m/s2.)

If a simple machine reduces the strength of a force, what must be increased?

Engines for propeller-driven aircraft are limited in their maximum rotational speed by the fact that the tip speed of the propeller must not approach the speed of sound in air (mach i). taking 6 ft as a typical diameter for a propeller of a light airplane and 1100 fils as the speed of sound, find the upper limit on the rpm (revolutions per minute) of the propeller shaft.
