A4.0-kilogram object is accelerated at 3.0 meters
per second2 north by an unbalanced force. the
same unbalanced force acting on a 2.0-kilogram
object will accelerate this object toward the north at
(1) 12 m/s2 (3) 3.0 m/s2
(2) 6.0 m/s2 (4) 1.5 m/s2

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

Suppose a soccer ball is kicked from the ground at an angle 20.0º above the horizontal at 8.00 m/s. the y-velocity is determined to be 2.74 m/s. how long will the ball be in the air? assume the ball lands at the same height at which it was kicked.

Consider two regions of space containing a static electric field, region a and region b. in region a the equipotential lines are more closely spaced than those in region b. what can be said about the relative strength of the electric field in the two regions? a) the electric field in region a is stronger th
