(a) Determine the work done by the elevator in ifting you and your belongings up to the 6th floor (15.2 m) at a constant velocity Work (b) How much work does the elevator do on you alone (without belongings) on the downward trip, which is also made at a constant velocity? Work Select... GO Tutorial Additional Materials 4 points CJ10 6 P006Explanation / Answer
Given,
w = 678 N ; W = 876 N
a)Fnet = w + W
Fnet = 678 + 876 = 1554 N
W = Fnet x d = 1554 x 15.2 = 23620.8 J
Hence, W = 23620.8 J = 2.36 x 10^4 J
b)For you alone
Fnet = w = 678 N
Wa = - 678 x 15.2 = -10305.6 J
Hence, Wa = 10305.6 J = - 1.03 x 10^4 N
