Question

20 POINTS TOTAL PLEASE HALP

The same force is applied to two skateboards. One rolls across the room and the other moves a few feet and comes to a stop. Where was there more work done?

Answer 1

one skateboard = rolls across the room

second skateboard = moves a few feet

the second skateboard is the one who worked more. there was more friction on the ground in which the skateboard couldn't glide across the room like the first one. friction is a force. the skateboard had to work harder to move across the room because of friction.

in other words, it's the skateboard that did NOT roll across the room worked harder

Answer 2

(I'm not 100% sure about these but I'm pretty sure)

Work is equal to Force*distance and since the same force was on both guys and one went further,

i hope this helps
