Q. A stone with a mass of 0.80 kg is attached to one end of a string 0.900 m long. The string would break if its tension exceeds 600-N. The stone is whirled in a horizontal circle on a frictionless tabletop; the other end of the string remains fixed. Determine the highest speed the stone can attain without breaking the string.
A 280 block on a 58 long string swings in a circle on a horizontal, frictionless table at 90.0 . What is the speed of the block.
The range of human hearing extends from approximately 20 Hz to 20000 Hz. Find out the wavelengths of these extremes while speed of sound in air is equal to 348 m/s.
How far away from the people is the plane.
What is the maximum speed with which a 1060kg car can round a turn of radius 75m on a flat road if the coefficient of static friction between tires and road is 0.80.
While standing on a bridge 45m above the ground, you drop a stone from rest. When the stone has fallen 4.90m, you throw a second stone straight down. What initial velocity should you give the second stone if they are both to reach the ground at th..
What is the beat frequency in Hz. A force of magnitude P pushes the block forward and downward as shown in the figure below. suppose the force is applied at an angle of 24.0° below the horizontal.
A 5m-diameter garden pond holds 5.90 times 10^ {3};{rm kg} of water.
the 25g bullet travelling at 350m/s strikes a block of wood. The block of wood exerts an average force of 50,000N opposing the motion of the bullet. How far does the bullet penetrate while stopping.
Each is afraid that one vine will break; as a result they grab each other and hang on. They swing upward together, reaching a point where the vines make an angle of 22.1° with the vertical. Find the value of the ratio m/M.
The driver of an 1800 kg car travelling at 23 m/s slams on the brakes, locking the wheels on the dry pavement. The coefficient of kinetic friction between rubber and dry concrete is typically 0.700.
A ship sets out to sail to a point 156 km due north. An unexpected storm blows the ship to a point 118 km due east of its starting point. How far should it now sail to reach its original destination.
