Urgent! An 80.0 kg crate is given an initial speed that sends it sliding up an inclined plane. The incline angle is θ = 12.0° and the coefficient of kinetic friction between the plane and the crate is 0.350. What is the observed acceleration of the crate as it slides along the incline?

The observed acceleration of the crate as it slides along the incline is -1.32 m/s².

Acceleration of the crate

The acceleration of the crate is determined from the net force acting on the crate as shown below.

F - Ff = ma

mgsinθ - μmgcosθ = ma

where;

  • m is mass of the crate
  • θ is  angle of inclination
  • g is acceleration due to gravity

(80)(9.8)(sin 12) - (0.35)(80)(9.8)cos(12) = 80a

-105.4 = 80a

a = -1.32 m/s²

Thus, the observed acceleration of the crate as it slides along the incline is -1.32 m/s².
