Q3: Need help with the 2 parts I got incorrect, pls help and I'll be sure to upvote. Thank you!

A statue is crated and moved for cleaning. The mass m of the statue and the crate is 150 kg. As the statue slides down a ramp inclined at an angle 0 = 40, the curator pushes up, PK parallel to the ramp's surface, so that the crate does not accelerate. The statue slides a distance d = 4.0 m down the ramp, as shown in the figure, and the coefficient of kinetic friction /k between the crate and the ramp is 0.52. Assume the that positive direction is down the ramp. d Calculate the work Wgrav done by the gravitational force. -3777.9 W grav = Incorrect Calculate the work Wfriction done by the friction force. Wfriction = -2342.24 Calculate the work Wcurator done by the curator. 6121.8 W curator Incorrect Calculate the work Wnormal done by the normal force. Wnormal = 0
