Question 7 - use this information to answer the following three questions A crate of mass 12.0 kg is pulled up a rough incline with an initial speed of 2.5 m/s. The pulling force is 130N parallel to the incline, which makes an angle of 30 with the horizontal. The coefficient of kinetic friction is 0.55 and the crate is pulled 8.0m. (a) How much work is done by gravity? (b) How much energy is lost because of friction? (c) How much work is done by the 130N force? Question 10 1 pts A crate of mass 12.0 kg is pulled up a rough incline with an initial speed of 2.5 m/s. The pulling force is 130N parallel to the incline, which makes an angle of 30 with the horizontal. The coefficient of kinetic friction is 0.55 and the crate is pulled 8.0m along the incline. (a) How much work is done by gravity (negative number)? Question 11 3 pts A crate of mass 12.0 kg is pulled up a rough incline with an initial speed of 2.5 m/s. The pulling force is 130N parallel to the incline, which makes an angle of 30 with the horizontal. The coefficient of kinetic friction is 0.55 and the crate is pulled 8.0m. (b) How much energy is lost because of friction (negative number)? Question 12 1 pts A crate of mass 12.0 kg is pulled up a rough incline with an initial speed of 2.5 m/s. The pulling force is 130N parallel to the incline, which makes an angle of 30 with the horizontal. The coefficient of kinetic friction is 0.55 and the crate is pulled 8.0m. (c) How much work is done by the 130N force
