1. A horizontal rope pulls a 20kg wood sled across frictionless snow. A 5 kg wood box rides on the sled. The coefficient of static friction for wood on wood is 0.5. What is the largest tension force for which the box doesn't slip?
m = 5 kg box, 20 kg sled
mu = .5
T = ?
2.
F = ma
Ff= mu x n
3.
F = ma
a of box is zero since it is not moving
T - mu x (20 + 5) x (9.8) = 0
