A 23kg sled is pulled by a rope. The sled has a frictional coefficient of 0.14 on snow. Find the tension in the ropeif the sled is accelerated at 2.7m/s^2

Question

Newton's Laws

Answer 1

Assuming the rope is pulled horizontally,

 

T = tension

f = magnitude of opposing friction = μmg

 

By Newton's 2nd law,

 

T - μmg = ma ⇒

 

T = m(a + μg)

 

You know m, a, μ, and g.  Just plug in the numbers and get T.
