A force in the +z-direction with magnitude 18.0 N- (0.530 N/m)z is applied to a 6.60 kg box F(x) that is sitting on the horizontal, frictionless surface of a frozen lake. F(x) is the only horizontal force on the box. O Part A If the box is initially at rest at r = 0, what is its speed after it has traveled 16.0 m ? Express your answer to three significant figures and include the appropriate units. ? HA Value Units Submit Previous Answers Request Answer

Cray-Zee is speeding along at 26 m/s as she approaches the level section of track near the loading dock of the Whizzer roller coaster ride. A braking system abruptly brings the 392-kg car (rider mas included) to a speed of 3 m/s over a distance of 5.7 meters Determine the magnitude (positive answer) of the braking force applied to Cray-Zee's car. Answer: N

A horizontal force of 80.0 N is applied to a 5.00 kg block as the block slides a distance of 0.800 m along a horizontal floor. The coefficient of kinetic friction between the floor and the block is 0.500. If the block is initially at rest, how fast is it moving at the end of the displacement?

A 2.0 kg object is moving to the right with a speed of 1.0 m/s when it experiences the force shown in the figure. What are the object’s speed and direction after the force ends? Express your answer to two significant figures and include the appropriate units. Enter positive value if the speed is directed to the right and negative value if the speed is directed to the left.
