0/1 pts Incorrect Question 2 The rotating systems shown in the figure differ only in that the two identical movable masses are positioned a distance r from the axis of rotation (left), or a distance r/2 from the axis of rotation (right) You release the hanging blocks simultaneously from rest, and call t, the time taken by the block on the left and tR the time taken by the block on the right to reach the bottom, respectively. The bar,...
18. Assuming the lower arm has a mass of 2.8 kg and its center of gravity is 12 cm from the elbow-joint pivot, how much force must the extensor muscle in the upper arm exert on the lower arm to hold a 7.5 kg shot put? 2.5 cm 30.0 cm- Elbow joint A) 100 N B) 500N C)750N D) 1000 N E) 1500 N 19. A boy and a girl are riding on a merry-go-round that is turning. The boy...

Need specific solutions for these questions, thank you~ 3. A 392-N wheel comes off a moving truck and rolls without slipping along a highway. At the bottom of a hill it is rotating at 25.0 rad/s. The radius of the wheel is 0.600 m, and its moment of inertia about its rotation axis is 0.800MR2 Friction does work on the wheel as it rolls up the hill to a stop, a height h above the bottom of the hill; this...
A SUV is moving away from you and negotiating a horizontal turn in the road as. The radius of the turn is 16 m and its center is on the right, indicated in the figure. The vehicle's center of gravity (cg) is h = 0.94 m above the ground and located midway between the wheels. The separation betwen the wheels is d = 1.7 m. What is the greatest speed at which the SUV can negotiate the turn without rolling...
15) A uniform marble rolls down a symmetrical bowl, starting from rest at the top of the left side. The top of each side is a distance h above the bottom of the bowl. The left half of the bowl is rough enough to cause the marble to roll without slipping, but the right half has no friction because it is coated with oil. (a) How far up the smooth side will the marble go, measured vertically from the bottom?...
Consider the block arrangement for the following situations: (a) Block moving upward at constant speed (b) Block moving downward at constant speed (c) Block moving upward, speed decreasing (d) Block moving upward, speed increasing (e) Block stationary it was like that i dont understand the question. help. Example 5.2.1 Sample Problem Block accelerating vertically This first figure shows a vertically moving block on the end of a cord. Example 5.2.1 Figure 1 This second figure gives the vertical velocity component...
Question 25 of 30 > A tightrope walker is walking between two buildings holding a pole with length L = 16.0 m, and mass mp-20.0 kg. The daredevil grips the pole with each hand a distance d = 0.500 m from the center of the pole. A bird of mass m 575 g lands on the very end of the left-hand side of the pole Assuming the daredevil applies upward forces with the left and right hands in a direction...
Consider a horizontal axis of rotation that passes through the center of the loop from left to right. Does the top wire of the loop want to rotate toward you (up from the table) or away from you (down into the table)? Away from you (down into the table Toward you (up from the table Previous Answers Correct Part B Calculate the magnitude of the torque about the axis described in part A Express your answer to two significant figures...
three coordinate system where x goes toward yourself and away from you, y goes right and left ways, and z goes up and down with + and - directions as seen in the figure. at ine point in time an electromagnetic wave has its E- firld in the -x direction and its B- firld in the +y direction. which direction is the wave moving +2 -DC ty -y - K to -2
