April works at the grocery store. she needs to move a heavy crate of bananas (m = 65 kg) to the produce section. she drags the crate along the floor by applying a force of 280 n at an angle of 35° above the horizontal.

a. if there is no friction, what is the acceleration of the crate? (5 points)
280/65=4.3
b. if the coefficient of kinetic friction between the crate and the floor is 0.4, what is the acceleration of the crate? (5 points)

Amoving company collects data about couches they move and displays the data in a table. the force along the ramp, the angle of the ramp, and the height the couch is raised to are shown. which statements correctly compare the work done to move the couches? check all that apply. the same amount of work is done for couches 1 and 3. the same amount of work is done for couches 2 and 3. the work for couch 1 is greater than the work for couch 2. the work for couch 2 is less than the work for couch 3. the work for couch 3 is greater than the work for couch 1. the work for couch 2 is greater than the work for couch 1.
