is .25 the accel and is the 38400 J right or wrong?

would it be 38400??

okay well i found the acceleration to be 4m/s2 then i found the distance to be 200m then i found the speed to be 40m but i think i did it wrong because i used the avg speed, sdo i put in E.K. = .5(50)(20)2 and got 1000 then E.K. = .5(50)(4)2 then go 400 i think i know why it's wrong but not sure

so then he lost 600 N to thermal energy right?

okay thank you very much

didn't get it , so use, a=(V2+V1(t))/2, then v=d/t, then divide the 2 then use those finidings to calculate the EK and EG?

that's how you find the average potential gravitational and kenetic energies, then i am able to find the themal heat given off right, just to tell you guys i have done both a and b,i'm just stuck on c, wasn't quite sure how to do it

i just need to know how to get the avg potential and kenetic energy? any help?

Could some one possible help me with the problem i have for physics, it was a test question and i didn't get it at all. A contestant will be required to pull a 50 Kg landing mat, from rest across the gym floor for 10 seconds. Mat has been selected for this event. he has calculated that if he...
