It decreases 1 of 8 An object falls from 2.5m above the ground from rest, what's it's velocity immediately before it hits the ground? 7 meters per second 2 of 8 A body of mass 2kg is acted on by a resultant force of 6N. What is its acceleration? 3 meters per second per second 3 of 8 State Newtons first Law A body will remain at constant velocity unless acted on by a resultant force 4 of 8 State Newtons third Law For every force, there is a similar force of equal but opposite magnitude 5 of 8 A woman pushes a trolley 12 meters with constant force 10 N. How much energy does she expend? 120 J 6 of 8 A motor does 200J of work in 10s. How much power does the motor evolve? 20W 7 of 8 A body of mass 5kg is acted on by a resultant force of 2N at 60 degrees to the horizontal. What is it's acceleration? 0.2 meters per second 8 of 8
