Moshe Haney · Answer 1

L=F*d

F=G=194 N

L=F*d=194*3.2=620.8 J

P=L/t=620.8/8.6=72.18 W

Raegan Franklin · Answer 2

Given that:

Force (F) = 194 N,

height (h) = 3.2 m = displacment

time (t) = 8.6 s,

Determine a). Work = ? b). Power = ?

a). Work = F * displacement

= 194 * 3.2

W = 620.8 J

b). Power (P) = Work : time

= 620.8 : 8.6

Power = 72.19 Watts
