Thankyou so much
26:33I dont get how work done against friction which I believe is final KE will be 450 J ? Shouldn't that 450 be the gPE
No. The energy reduces by the amount equal to the work done by friction. So the initial energy what ever form it may be reduces by 1300
Sir, can I solve question number 10 with the formula F=ma ?
Yes, you can
Thankyou so much
