Answer:
when they have the same slope
Answer:
= 2630.6 N.m
Explanation:
(FR)x = ΣFx = -F4 = -407 N
(FR)y = ΣFy =-F1-F2 -F3 = -510 - 306 - 501 = -1317 N
(MR)B =ΣM + Σ(±Fd)
= MA + F1(d1 +d2) + F2d2 - F4d3
= 1504 + 510(0.880+1.11) +306(1.11) - 407(0.560)
= 2630.64 N.m (counterclockwise)
3 because opposites attract
Explanation:
The velocity is not needed. (its needed to find kinetic energy but its irrelevant to the question)
Potential energy = Mgh
Mass=5kg, height=10meters, g=9.8
P.e=5×9.8×10
=5×98
=490 joules
