The board sandwiched between two other boards in Figure P5.97 weighs 95.5 N. If the coefficient of static friction between the boards is 0.663, what must be the magnitude of the compression forces (assumed horizontal) acting on both sides of the center board to keep it from slipping?
In a tape recorder, the tape is pulled past the read-write heads at a constant speed by the drive mechanism. Consider the reel from which the tape is pulled: As the tape is pulled off, the radius of the roll of remaining tape decreases, (a) How does the torque on the reel change with time? (b) If the tape mechanism is suddenly turned on so that the tape is quickly pulled with a large force, is the tape more likely to break when pulled from a nearly full reel or from a nearly empty reel?
A steel ball is dropped onto a hard floor from a height of 1.50 m and rebounds to a height of 1.45 m. (a) Calculate its velocity just before it strikes the floor. (b) Calculate its velocity just after it leaves the floor on its way back up. (c) Calculate its acceleration during contact with the floor if that contact lasts (8.00105s). (d) How much did the ball compress during its collision with the floor, assuming the floor is absolutely rigid?

1) Two children push on opposite sides of a door during play. Both push horizontally and perpendicular to the door. One child pushes with a force of 175 N at a distance of 0.400 m from the hinges, and the second pushes at a distance of 0.450 m. What force (in N) must the second exert to keep the door from moving? Assume friction is negligible. _____ N

At an amusement park there is a ride in which cylindrically shaped chambers spin around a central axis. People sit in seats facing the axis, their backs against the outer wall. At one instant the outer wall moves at a speed of 3.16 m/s, and an 85.3-kg person feels a 546-N force pressing against his back. What is the radius of a chamber?

QUESTION 1 Problem A solid uniform ball with mass m and diameter d is supported against a vertical frictionless wall by a thin massless wire of length L. a) Find the tension in the wire. Solution a) Let us first derive the expression for the tension. By Newton's First Law ΣF = ______ the components of force that makes this so is ΣF = T_____ -_____ = 0 Simplifying this results to T =________ g/_____(ϕ) Analyzing the figure above, we arrive at (ϕ) = sqrt(_____ 2 +______ ) / (_____ /_____ +_____ ) By substitution, we arrive at the following: T = (_____ + 2______ ) g / ( ______ sqrt (______ 2 +_____ ) ) If the ball has a mass of 45 kg and diameter 32 cm, while the wire has a length of 30 cm. The tension is equal to T = ________ 0.370 N
