36 unit squares are joined to form a rectangle with least perimeter what is the perimeter of rectangle?
ok so i solved for 1a) first i used the ep=mgh formula to get 68J then i plugged that in the Ek=1/2 mv^2 formula and got 4.8 m/s but i'm stuck on b) and c) can u please help
ok so here's how i thought i would have to solve these: 1. W=mgh =100*9.8*2.0 or w=0 because u lift the mass upards and carry it (perpenticular ) hence w=0 2. W=f delta D W/D=Force 3. W=60N * 40cm (ordo i convert 40 cm to kg) 4. W=mgh W/h=m (do i convert
you don't understand i don't get this unit and i'm failling this unit miserabely really need help
when i divided 2.3/(1.4*9.8) i got 0.1676 and for quesiton 1 do u mean that a) will be 0J sinse it is rest on the desktop and b) will be 2.8 J
