Question

A sled with a weight of 200N is being pulled from rest by a force of 40 N across ice which has a coefficient of kinetic friction of ,070. If air resistance is negligible, find the acceleration of the sled. How far will the sled slide in 6 Sec?

Answer 1

net force= mass*acceleration
where net force= pulling force -mg*mu

Answer 2

net force (F) = 40 - (0.07*200) = 26 N

acceleration (a) = F/m = 26/(200/g)
= 1.27 m/s^2

Sliding distance in time t = (1/2) a t^2

Answer 3

23m
