i have made a try i even made a drawing but its still hard...

A Ball Is Held Above A Spinning Circular Platform. The Ball Is 1.3m Above The Circular Platform That Has A Diameter Of .67m And Makes One Complete Revolution In 2.5 Seconds. If The Platfom Has A Hole On The Edge Where The Fall Can Get Through And The Ball Falls At 1.8 M/s...when Should The Ball...

a baseball player hits a home run that just clears the top of the bleachers 21m high located 130m from home base. the ball is hit at an angle of 35* above the horizontal a) find initial velocity of the ball b)the total time of the flight of the ball...

i don't know how to plug in the numbers

i don't know help me get started u drew a picture with all of the diagrams,,,, but i don't know how to set up the problem because i have to use the conservation of energy principles.

i did and i get 9142400 a huge number...but i won't get any credit if don't use the conservation of energy principles...

yeah but i can't use those beacuse the teacher said to use the principles of energy of conservation

aw man i don't know...

i did (1/2)(.02)(800)^2 / (.56) =11428

a force of 120N pushes a 5kg block up an incline plane (20 degrees) at a constant velocity. given information find coefficient of kinetic friction between block and incline

know i do after i read that thing from wikipedia... then wat do i do

so i get (1/2)V^2 / "mu" G = delta s

is it (1/2)MV^2 - (1/)MV^2

ok this is what i get (1/2)MV^2 / "mu"MG = delta s

this is wat i got then (-750v^2) / (735) =delta s
