P = W/T , W = FxS ,
F = ma
= 60x9.8
F = 588 N [sub in W = FxS]
W = FxS
= 588x10
W = 5880 [sub in P = W/T]
P = 5880/5
ans: P = 1176 W
F = ma
= 60x9.8
F = 588 N [sub in W = FxS]
W = FxS
= 588x10
W = 5880 [sub in P = W/T]
P = 5880/5
ans: P = 1176 W
jkeasy111:
W = work done , T = time taken , F = force , S = displacement [ here vertical displacement
m = mass , a = acceleration [ here g = acceleration due to gravity ]
intend of ma mg .
