Dynamics: Question 1 of 4
 A net force of 10. newtons accelerates an object at 5.0 meters per second2. What net force would be required to accelerate the same object at 1.0 meter per second2? 1.0 N 2.0 N 5.0 N 50. N Correct Answer Number: 2 Explanation: Use the equation m=F/a (F=ma) to calculate the mass of the object, then use F=ma (F=2kg x 1m/s2)to find the force.

Dynamics: Question 2 of 4
 A 2.0 x 103-kilogram car travels at a constant speed of 12 meters per second around a circular curve of radius 30. meters. What is the magnitude of the centripetal acceleration of the car as it goes around the curve? 0.40 m/s2 4.8 m/s2 800 m/s2 9,600 m/s2 Correct Answer Number: 2 Explanation: Centripital acceleration is v2/r

Dynamics: Question 3 of 4
 A 2.0 x 103-kilogram car travels at a constant speed of 12 meters per second around a circular curve of radius 30. meters. As the car goes around the curve, the centripetal force is directed toward the center of the circular curve away from the center of the circular curve tangent to the curve in the direction of motion tangent to the curve opposite the direction of motion Correct Answer Number: 1 Explanation: centripetal force, and centripetal acceleration, always point in toward the center of the circle.

Dynamics: Question 4 of 4
 The amount of work done against friction to slide a box in a straight line across a uniform, horizontal floor depends most on the time taken to move the box distance the box is moved speed of the box direction of the box’s motion Correct Answer Number: 2 Explanation: Basic equation W=F x d. the work is dependent on the distance the box is moved.
