a. object 1 exerts a 10 newton force on object 2 in the direction of its 1 meter displacement.
b. object 1 exerts a 1 newton force on object 2 in the direction of its 10 meter displacement.
c. object 1 exerts a 10 newton force at a 60 degree angle relative to its 2 meter displacement.
d. all of the above are true.
e. only two of the above are true.
f. none of the above are true.

Select the correct answer. what does the process of natural selection involve?

Choose a realistic problem for which these are the correct freebody diagrams. be sure that the answer that the problem requests is consistent with the diagrams shown. choose a realistic problem for which these are the correct freebody diagrams. be sure that the answer that the problem requests is consistent with the diagrams shown. a 1.0 kg block is placed on top of a 2.0 kg block. a horizontal rope pulls the 2.0 kg block across a frictionless floor with a force of 21.0 n. the coefficient between the two blocks is 0.75. does the 1.0 kg block on top slide?

Using the free-body diagram, calculate the net force acting on the sled. is the sled in a state of dynamic equilibrium?
