Q. A rock stuck in the tread of a 59.0 cm diameter bicycle wheel has a tangential speed of 3.20 m/s. When the brakes are applied, the rock's tangential deceleration is 1.20 m/s^2
Q. A 202-kg projectile, fired with a speed of 123 m/s at a 53.0 angle, breaks into three pieces of equal mass at the highest point of its arc (where its velocity is horizontal). Two of the fragments move with the same speed right after the explosion as the entire projectile had just before the explosion; one of these moves vertically downward and the other horizontally.
A.Determine the magnitude of the velocity of the third fragment immediately after the explosion.
B.Determine the direction of the velocity of the third fragment immediately after the explosion. (find theta above the horizontal)
C.Determine the energy released in the explosion.
Find out the magnitude and direction of the displacement
A 5.00 X 10-2 kg mass with a charge of +0.75 mC is hung by a thin insulated thread. A charge of -0.9 mC is held 0.15 meters directly to right so that the thread makes an angle q with the vertical. What is the angle q and the tension in the string.
Two identical pellet guns are fired simultaneously from the edge of a cliff. These guns impart an initial speed of 24.1 m/s to each pellet. Gun A is fired straight upward, with the pellet going up and then falling back down, eventually hitting the..
The concrete encloses one steel reinforcing rod with cross-sectional area 1.00cm2. The rod joins two strong end plates. The cross-sectional area of the concrete perpendicular to the rod is 47.5 cm2. Young's modulus for the concrete is 3.00 x 10^10 N/..
A helicopter is ascending vertically with the speed of 5.79. At a height of 127 above the Earth, a package is dropped from a window. How long take the package to hit the ground.
The object is authorized to move on a horizontal frictionless surface. The object is released from rest when the spring is compressed 0.15 m. Find out the force on the object.
A spelunker is surveying a cave. She follows a passage that takes her a distance 189 straight west, then a distance 220 in a direction 45 east of south, after that a distance 280 at 30 east of north. After a fourth unmeasured displacement she find..
