Question 1 (1 point) The force of gravity affects only the vertical component of the velocity of a projectile and not the horizontal component of the velocity. True O FalseQuestion 3 (1 point) Saved A student walks 50.0m [W60N]. Which pair of displacements represent the same vector? 30.0m [W] and 40.0m[N] ( 40.0m[W] and 30.0m[W] 25.0m[W] and 43.3m[N] (43.3m[W] and 25.0m[N] Question 4 (1 point) Saved A 61kg gymnast falls vertically from a jump onto a trampoline. Her speed as she hits the trampoline is 5.2m/s and she comes to a stop in 0.20s. What is the average magnitude of the force exerted on the gymnast by the trampoline? O 6.1N 305N 610N O 160ONQuestion 6 {1 point] A 0.3kg soccer ball is released from the top of a 10m building. The ball strikes the ground with a speed of 12mfs. Use the conservation of energy to determine the energy lost due to the work done by air resistance. .3. 13.2J Q. 21.6J Q 29.4J Question ? {1 point] Saved What provides the centripetal force for a car moving around in a circle on a banked curve covered with very slippery ice? .5) friction between the tires and backed curve \\ (:3. the horizontal component of the normal force F). the vertical component of the normal force K- C). the weight of the car Question 8 {1 point} An object is in a state of equilibrium when the net force acting on it is zero. Question 9 {1 point} Saved A race car brakes and skids to a stop on the road. Which statement best describes what happens? O The race car does work on the road 6) The friction of the road does negative work on the race car. O The race car and the road do equal work on each other. 0 Neither does work on the other. lQuestion 1D {1 point] 1Which of the following describes a situation explained bv Newton's third law? O a person pushes left on a wall while the wall pushes right on a person O clothes in a washing machine moving to the edge of the drum during the spin cvcle O a spacecraft moving far from am-r massive bodies a car accelerating forward by an amount equal to the ratio of the net forward force and the mass of the car Question 12 {1 point] Acceleration always occurs in the same direction as the motion of the object. {3: True {22} False Question 13 {4 points} A space probe far from anyr planets and stars requires a force of 1.2x10"3 N to accelerate at 2.4mfsn2. Determine the force needed to accelerate the probe at the same rate all-wallr from the Earth's surface during launch. Paragraph v Lato [Recom... v
