A sled and its rider are moving at a speed of 4.0 m/s along a horizontal stretch of snow. The snow exerts a kinetic frictional force on the runners of the sled, so the sled slows down and eventually comes to a stop. The coefficient of kinetic friction is 0.050. Determine the acceleration of the sled.

Cricetus

Answer:

The acceleration of the sled is "0.49 m/s²". A further explanation is given below.

Explanation:

The given values are,

Speed,

V = 4.0 m/s

Coefficient of kinetic friction,

μ = 0.05

As we know,

⇒  [tex]F \mu=\mu mg[/tex]

and,

⇒  [tex]a = \mu g[/tex]

On substituting the given values, we get

⇒     [tex]=0.0 5\times 9.8[/tex]

⇒     [tex]=0.49 \ m/s^2[/tex]
