Choose the situation below in which the force applied is the greatest.
A) Steve put in 50 J of work moving a box 50 meters.
B) Doing 400 J of work, Penny pushed her cat 80 meters.
C) Samantha did 365 J of work dragging a wagon across 73 meters of lawn.
Eliminate
D) Clark pushed a crate from the chair, 16 meters across the room, doing 144 J of work.

Mass (kg) force (n) 5 25 10 50 15 75 20 100 a student was trying to find the relationship between mass and force. he placed four different masses on a table and pulled them using a spring scale. the table shows the different masses used in the experiment and the force required to pull each mass. the student concluded that more force was required to pull heavier objects. what comment would you make regarding his conclusion? a) no clear relation can be observed between mass and force from the data. b) there is a direct proportion between the mass and force listed in the table. c) gravity should have been taken into account while performing the experiment. d) there is an inverse proportion between the mass and force listed in the table.

5g of ammonium nitrate was dissolved in 60g of water in an insulated container. the temperature at the start of the reaction was 23.0°c and at the end it was 19.0°c. calculate the energy absorbed by the reaction.

If the force applied to an object remains constant, is more power needed for the object to move faster ? explain
