Transcribed Image Text:AP AP Classroom Unit 5 Progress Check: MCQ Part A Question 12 A +00 2 3 5 6 9 -17 Graph of f' The graph of f' the derivative of the function f, is shown above for 0 . Block X and block Y are tied together by a rope. Cart X with a mass of 1kg is released from rest at the top of an inclined ramp, and the cart rolls down the ramp with negligible friction. Define vocalics and differentiate among the AP A graph of the force that object X exerts on object Y is shown. Answer: In this case, it is the friction between the coin and the surface of the turntable that keeps the coin from sliding. After the collision, masses M1 and M2 slide together up the curved ramp as a total mass of M12 , as shown in Figure 2. In trial 1, the student exerts the force on a cart of mass M.

The block has an initial momentum 18kgms. While we do not know how high the ax head was when it fell into the water, we will work, Any help would be really appreciated - this is AP Physics 2: Fluids 5 m 3 m 2 m/s D 4 m Vb (10 points, suggested time 20 minutes) One section of a 5 m wide irrigation channel that is filled with. The skier reaches point C traveling at WebA 5 kg object near Earth's surface is released from rest such that it falls a distance of 10 m. After the object falls 10 m, it has a speed of 12 m/s. Block X and block Y travel toward each other along a horizontal surface with block X traveling in the positive direction. No, because the slope of the curve of the graph indicates that the acceleration is less than gg, which indicates that a force other than gravity is exerted on the object. The normal force for the riders is greater than the weight of the riders, mg. B. A ski jumper starts from rest from point A at the top of a hill that is a height h1 above point B at the bottom of the A block of mass of 10kg travels in the positive direction along a surface with negligible friction. The skier and skis have a combined mass of 80 kg. A vessel contains a mixture of gases. A student must perform an experiment in which two objects travel toward each other and collide so that the data collected can be used to show that the collision is elastic within the acceptable range of experimental uncertainty. Answer: For this question you should use F = G(m1*m2)/r^2. The tricky part of the math is that you need to recognize the 2.0 m is the diameter and not the radius of the circle. Student XX ties one end of a string to a 0.50.5 kgkg ball and swings the ball in a vertical circle of radius 1 m1 m, as shown in the figure. All experiments have the same change in momentum for the center of mass of the system of two carts. APHG Unit 5 MCQ Progress Check : r/APStudents - reddit (a) Calculate the height h1. Since both masses double, Fnew ~ 2m*2m = 4*Foriginal. of is the same as Multiple Choice Questions 13. The normal force for the riders is smaller in magnitude than their weight, mg. C. The riders are getting "pushed down" in their seats and therefore feel heavier at point "b". Two golf balls, 1 and 2, attract each other gravitationally with a force of magnitude F. If we now double both masses but leave the radius the same, what will now be the magnitude of the attractive force on each one?
