Answer to Question #144877 in Classical Mechanics for KRistin Marston

Question

A moose is pulling a heavy sled through the snow (with friction). The sled has a mass of 65 kg. The moose applies a force of 780 N to the sled. The coefficient of kinetic friction between the sled and the snow is 0.26.

Answer 1

Answer

Friction force=$\mu mg\\=0.26\times65\times9.81\\=165.78N$

Applied force(F) =780N

Acceleration can be given as

$F-f=ma\\a=\frac{780-165.78}{65}\\a=9.45m/s^2$
