My Notes Ask In 1990 Walter Arfeuille of Belglum lifted a 281.5-kg object through a distance of 17.1 cm using only his teeth (a) How much work did Arfeuille do on the object? 472.21 (b) What magnitude force did he exert on the object during the lift, assuming the force is constant. Your response is off by a multiple of ten. kN Need Help? Raad It ||Talk to a Tutor | My Notes +Ask Your Teacher 2. 2/4 points I Previous Answers SerCP8 5.P.005. Starting from rest, a 5.2-kg block slides 2.20 m down a rough 30.0° incline. The coefficient of Hk 0.436. 0 m down a rough 30.0° incline. The coefficient of kinetic friction between the block and the incline is
Explanation / Answer
here,
mass , m = 281.5 kg
s = 0.171 m
a)
work = 472.21 J
b)
the magnitude of force exerted on object , F = m * g
F = 281.25 * 9.81 N
F = 2759 N = 2.76 KN
