A 54.0-kg crate rests on a level floor at a shipping dock. The coefficients of static and kinetic friction are 0.614 and 0.310, respectively. What horizontal pushing force is required to (a) just start the crate moving and (b) slide the crate across the dock at a constant speed?

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

it breaks and dirupture other materials and other sencews from the bottom

the duration of a photographic flash is related to an rc time constant, which is 0.100 μs for a certain camera.

the journeys of marquette, joliet and la salle a) new france expand.

all three of these explorers explored the midwest and the area around the great lakes, which they subsequently claimed for france.

this was a big portion of territory and expanded new france which before then only consisted of quebec province in northeastern canada
