1. The problem statement, all variables and given/known data A crate is pulled by a force (parallel to the incline) up a rough incline. The crate has an initial speed shown in the figure below. The crate is pulled a distance of 9.33 m on the incline by a 150 N force. The acceleration of gravity is 9.8 m/s 2 . What is the change in kinetic energy of the crate? Answer in units of J. Mass = 11kg Angle of the incline (θ)= 20° Initial Velocity = 1.55 m/s μ = .308 D= 9.33 Meters Force Applied = 150N g=9.8 2. Relevant equations Ff= μN W=Fd=ΔKE Fapplied -Ff=Fnetx FnetVertical =0 3. The attempt at a solution N-mgcosθ=0 N=mgcosθ Fa-Ff=Fnet Fa-μN Fa-μmgcosθ=Fnet 150-(.308)(11)(9.8)cos(20°)=118.8 W=ΔKE = 118.8(9.33) = 1399.5 Not sure what I am missing but it is incorrect.
