Aforce of 15 n acts upon a 3 kg block. calculate the acceleration of the object.
question 2 options:
a. 75 m/s^2
b. 5 m/s^2
c. 45 m/s^2
d. 18 m/s^2

Write the equation for momentum, first using symbols for the variables, then using words for the variables.

Imagine that someone pushes one marble toward a motionless marble. would there still be action-reaction forces involved in the collision? how might the marbles’ motions be changed? ?

Suppose you have a box. which of these is not necessarily a true statement regarding the relationship between the force applied to the box, the work done on the box, and the distance the box is moved? a. if the box is not moved, no force is being applied to the box. b. if no force is applied to the box, no work is done on the box. c. if work is done on the box, then a force is applied to the box. d. if work is done on the box, then the box is moved a distance.
