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

Alex Morgan, one of America's best forwards, kicks a 450. g soccer ball that was moving towards her at a speed of 12.0m/s, the impact caused the ball to leave her foot with a velocity of 20.0 m/s in the opposite direction. a. If the impact lasted for 0.250s, what force (magnitude and direction) did Alex exert on the soccer ball? b. What is one thing that she could do to make the soccer ball have a larger change in momentum?

Question 4 Problem: An escalator is used to move exactly 8 Question 3 Problem: An escalator is used to move exactly 8 passengers per minute from the first floor of a department store to the second floor. The passengers per minute from the first floor of a department store to the second floor. The second floor is located 5.2 meters above the first second floor is located 5.20 meters above the floor. The average passenger's mass is 54.9 kg. Determine the power requirement of the first floor. The average passenger's mass is 54.9 kg. Determine the power requirement of the escalator in order to move this number of escalator in order to move this number of passengers in this amount of time.

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.

g Anderson Video - Work Done by a Spring A block of mass 0.2 kg is launched by a spring k₁= 2.0 N/m as shown below. The block moves along a frictionless horizontal table and pushes another spring, k₂= 2.3 N/m, to the maximum deflection z. If the initial deflection of the spring k, is 0.050 m, what is the maximum deflection of spring k₂? Consider that the masses of the springs are negligible. Express your answer with the appropriate units. T= μA Value ▬▬ Units ? k₁ T P Pearson 4 of 14 k2 m > ▸

QUESTION 8 Your mass is 94.1 kg, and the sled s mass is 20.1 kg. You start at rest, and then you jump off the sled, after which the empty sled is traveling at a speed of 3.45 m/s. What will be your speed on the ice after jumping off?   A 1.04 m/s   B 0.89 m/s   C 0.74 m/s   D 0.37 m/s

Yolanda is at the firing range practicing how to shoot a gun. A 12 g bullet is fired from her gun and moves vertically upwards at a velocity of 950m/s and strikes a 2kg brick which is originally at rest, as shown in the picture below. If the bullet emerges from the brick at a speed of 290m/s, help Yolanda figure out; 1. What is the The max height to which the brick rises ? 2. What is The increase in the internal energy of the bullet-brick system? 290 m/s 950 m/s
