Answer #1

f m=10kg, d=3m, G=30°, F=80N, f= 22N (as Wp = fd = (80) (3) - 1240 J ) o b Wq = - f d sing = -(1089.8) (3) sim 90° = -147 J)

Please post the other questions separately. Thanks and good luck:)

    Hi, please help me check my answers for two physics problems. If they are wrong, please explain it so I could learn and correct the mistake. Thank you. [For the first problem, I got: push= 2598J, normal= 0, weight= 0, friction= -1920J. I calculated net work to be 678J ] [For the second problem, I got push=250J, normal and weight= 0, friction = -200J. I calculated net force to be 50J, which is positive] 3.
