▼ A 69 g ice cube can slide without friction up and down a 30° slope. The ice cube is pressed against a spring at the bottom of the slope, compressing the spring 10 cm. The spring constant is 21 N/m . When the ice cube is released, what total distance will it travel up the slope before reversing direction? Express your answer to two significant figures and include the appropriate units. As = μA Part B Value X Incorrect; Try Again Submit Previous Answers Request Answer As = |m The ice cube is replaced by a 69 g plastic cube whose coefficient of kinetic friction is 0.20. How far will the plastic cube travel up the slope? Express your answer to two significant figures and include the appropriate units. μÀ Value M Units ?
the child has a mass of 23.7kg. The chains each have a length of 3.22m. As the child swings, she moves along a path which is part of a vertical circle.When the child is at the lowest point of the swinging path, the chains exert a total upward force of 366N and the child's speed is ________m/s.Note: Speed is always a positive number.
A skier is sliding downhill at 7 m/s when she reaches an icy patch on which her skis move freely with negligible friction. The difference in altitude between the top of the icy patch and its bottom is 9 m. What is the speed of the skier at the bottom of the icy patch in m/s? Take g = 9.8 m/s. Round to one decimal place. (hint: do you have to know her mass?) %3D
A desperate hiker has to think fast to help his friend who has fallen below him. Quickly, he ties a rope to a rock of mass ma and makes his way over the ledge (see the figure). If the coefficient of maximum static friction between the rock and the ground is µ, and the mass of the hiker is mâ, what is the maximum mass of the friend, mc, that the rock can hold so the hikers can then make their way up over the ledge? Assume the rope is parallel to the ground and the point where the rope passes over the ledge is frictionless. mc = Ju

17. A few weeks ago in lab you were releasing gliders down a tilted frictionless air track. Assume the track surface is tilted by 18 degrees from the horizontal. The glider is released from rest at t=0, and passes through a gate, which is a distance d along the track from the starting position, 0.90 seconds later. What is d (to 2 sig.figs)? A) 1.6 m B) 4.0 m 日:18° 3.8 m D) 2.5 m E) 1.2 m 9 COS 18
2. The small cart has a speed V, = 4 m/s at point A. Neglecting friction, determine its speed va as it passes point B. Is knowledge of the shape of the track necessary? -4 mis 18 m
A pendulum is 0.850 m long, and the bob has a mass of 1.00 kg. At the bottom of its swing, the bob’s speed is 1.60 m/s. A) What is the tension in the string at the bottom of the swing? in N B)The tension is greater than the weight of the bob because a- its horizontal component is increasing from zero. b-the bob has a downward acceleration, so the net Fy must be downward. c- the bob has an upward acceleration, so the net Fy must be upward. d- the bob has zero acceleration.
Tarzan wants to use a vine to swing over a canyon to get to the other side of a cliff. He is able to exert a maximum force of 1330 N on the vine, what is the fastest speed Tarzan can have at the lowest point of his swing? His mass is 76.6 kg and the vine is 4.5 m long. (Answer to 1 decimal place and take g = 9.8m/s2)
Let's consider the system given in Figure 2. The end of a flexible spring with spring constant k is attached to the wall and the other end to a block of mass m. There is no friction between the block and the inclined plane. When the spring is at its natural length, the block is first decelerated. The angle of inclination of the inclined plane is given as ß. a) What is the acceleration of the blog when the spring is extended by x?
A small block slides down a frictionless track whose shape is described by y = (x^2) /d for x<0 and by y = -(x^2)/d for x>0.  d = 3.25 m. You start the block on the track at rest, somewhere to the left of x = 0. You then release the block from rest and let it slide down. What is the maximum value of x (that is, what is the closest to the origin) from which you can release the block from rest and have it leave the track at x = 0 and go into freefall? -1.63 m -1.15 m -1.39 m -1.52 m
