A squirrel is pushing on a 0.72 kg peach that is sitting on the grass. The peach accelerated by a net force of 8.0 N [E]. The force of friction on the peach is 3.0 N [W].
(a) Draw a free body diagram for the peach.
(b) Calculate the acceleration of the peach.
(c) Calculate the applied force that the squirrel applies to the peach to overcome friction and
accelerate the peach.

Look at the potential energy diagram for a chemical reaction. which statement correctly describes the energy changes that occur in the forward reaction?

An engineer designs a roller coaster so that a car travels horizontally for 162 ft, then climbs 127 ft at an angle of 31.0° above the horizontal. it then moves 127 ft at an angle of 46.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)
