You apply a constant positive force on an object for 2 seconds. After this 2 seconds, friction acts on the object. Which statement best describes the motion of the object after those 2 seconds.? a. The object will come to a stop immediately after you stop applying the force.
b. The object will slow down and come to a stop.
c. The object will move at a constant velocity.
d. The object will continue to speed up

When does your body conduct current more readily?

Explain the comparisons between nature and packingtown that appears on pages 81 and 82 answer

Aparticle's position is given by x = 3.00 - 9.00t + 3t2, in which x is in meters and t is in seconds. (a) what is its velocity at t = 1 s? (b) is it moving in the positive or negative direction of x just then? (c) what is its speed just then? (d) is the speed increasing or decreasing just then? (try answering the next two questions without further calculation.) (e) is there ever an instant when the velocity is zero? if so, give the time t; if not, answer "0". (f) is there a time after t = 3 s when the particle is moving in the negative direction of x? if so, give the time t; if not, answer "0".
