As a prank, someone has balanced a pumpkin at the highest point of a grain silo. The silo is toppedwith a hemispherical cap that is frictionless when wet. The line from the center of curvature of the capto the pumpkin makes an angle 6, = 0 with the vertical. While you happen to be standing nearby in themiddle of a rainy night, a breath of wind makes the pumpkin start sliding downward from rest. It losescontact with the cap when the line from the center of the hemisphere to the pumpkin makes a certainangle with the vertical. What is this angle? (48.2 degrees)

We need to determine the angle made with the vertical when the pumpkin loses contact with the…

A skateboarder is attempting to make a circular arc of radius r = 19 m in a parking lot. The total mass of the skateboard and skateboarder is m = 87 kg. The coefficient of static friction between the surface of the parking lot and the wheels of the skateboard is us= 0.68 . 1)What is the maximum speed, he can travel through the arc without slipping? 2)He speeds up very slightly and begins to slide. The coefficient of kinetic friction is uk = 0.13. What is the new magnitude, of his radial acceleration?
A speedboat with a mass of 505 kg (including the driver) is tethered to a fixed buoy by a strong 29.7 m cable. The boat's owner loves high speed, but does not really want to go anywhere. So the owner revs up the boat's engine, makes a lot of noise, and runs the boat in circles around the buoy with the cable supplying all the necessary centripetal force. When the tension of the cable is steady at 12300 N, with what force is the boat's engine pushing the boat? Different physics textbooks treat drag force somewhat differently and use different formulas. For the present purpose, take the water's drag force on the boat to be (450 kg/m) × v², where v denotes the boat's speed. Ignore any drag force on the cable. force: N & TOOLS x10
For a meter stick of mass 147.89 g, it is found that its weight can be balanced by hanging a 183.99 g mass at the 95.00 cm mark. Where does the center of the weight of the meter stick locate on the meter stick? Enter the number in cm unit.
A ladder leans against a wall 5 meters above the ground so a homeowner can clear his gutters of leaves from last fall. The bottom of the ladder just begins to slip when it is 1.7 meters from the wall. What is the coefficient of static friction between the bottom of the ladder and the ground?
The accompanying figure shows a frictionless channel in the shape of a segment of a circle with center at "O". The channel has been anchored to a frictionless horizontal tabletop. You are looking down at the table. Forces exerted by the air are negligible. A ball is shot at high speed into the channel at "p" and exits at "r." Consider the following distinct forces: A downward force of gravity. A force exerted by the channel pointing from q to O. A force in the direction of motion. A force pointing from O to q. Which of the above forces is (are) acting on the ball when it is within the frictionless channel at position "q"?
A 10 m long board has a mass of 7 kg. The left end of the board is against a wall and it sticks straight out like a boom. A rope is tied 1 m from the right end of the board and makes a 44 degree angle with the boom. A 25 kg box hangs 3 m from the right end. Find the tension in the rope.
A horizontal uniform meter stick supported at the 50-cm mark has a mass of 0.50 kg hanging from it at the 20-cm mark and a 0.30 kg mass hanging from it at the 60-cm mark. Determine the position on the meter stick at which one would hang a third mass of 0.60 kg to keep the meter stick balanced. Question 14 options: 74 cm 65 cm 62 cm 70 cm 86 cm
A 1.5-lb slider is propelled upward at A along the fixed curved bar which lies in a vertical plane. If the slider is observed to have a speed of 10.6 ft/sec as it passes position B, determine (a) the magnitude N of the force exerted by the fixed rod on the slider and (b) the rate v at which the speed of the slider is changing (positive if speeding up, negative if slowing down). Assume that friction is negligible. 29 2.8' Answers: N = Ib i ft/sec?
A particle of dust lands 48.8 mm from the center of a compact disc (CD) that is 120 mm in diameter. The CD speeds up from rest, and the dust particle is ejected when the CD is rotating at 98.0 revolutions per minute. What is the coefficient of static friction between the particle and the surface of the CD?
You have applied for a great summer job working with a special effects team at a movie studio. As part of your interview you have been asked to evaluate the design for a stunt in a new Indiana Jones production. A large spherical boulder starts from rest and rolls down an inclined track. At the bottom, the track curves up into a vertical circle so that the boulder can roll around on the inside of the circle and come back to ground level. It is important that the boulder not fall off the track at the top of the circle and crush the star standing below. You have been asked to determine the relationship between the heights of the boulder’s starting point on the ramp (measured from the center of the boulder) and the maximum radius of the circular part of the track. You can determine the mass and the radius of the boulder should you need to know them. You have been told that the moment of inertia of a sphere is 2/5 that of a ring of the same mass and radius. After some thought you…
Can you help? I am stuck! Two simple pendulums of equal length l = 0.45 m are suspended from the same point. The pendulum bobs are small solid steel spheres. The first bob is drawn back to make a 35° angle with the vertical, while the other one is left hanging at rest. If the first bob has a mass of 0.25 kg and the second has a mass of 0.54 kg, how high will the second bob rise above its initial position when struck elastically by the first bob after it is released?
