force of friction on the cart is given as

here we also know the reaction force due to surface

so we can say reaction force is given as




now by force balance we will say



also we know that



now minimum force required to set this into motion

here we know that



So it will require 259 N minimum force to move it

mass =
= 9.7 kg
Answer:
60.2 J
Explanation:
Efficiency is the ratio of work out to work in.
e = Wout / Win
0.86 = Wout / 70 J
Wout = 60.2 J
