A2.2 × 103
kg car accelerates from rest under
the action of two forces. one is a forward
force of 1147 n provided by traction between
the wheels and the road. the other is a 934 n
resistive force due to various frictional forces.
how far must the car travel for its speed to
reach 2.2 m/s?

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.
