Q. When objects are moved through a very viscous fluid, they experience drag proportional to their velocity:
F_drag = kA(roh)v;
for A is the cross sectional area of the object, roh is the density of the fluid and v is the speed of the moving object
let k be a constant,
write out Newton's Second Law for the velocity of the cube, and solve with an initial velocity of 0.
Two 5000 kg passenger cars roll without friction (one at 1 m/s, the other at 2 m/s) toward one another on a level track. They collide, couple, and roll away together with the combined momentum.
A person of mass 75 stands at the center of a rotating merry-go-round platform of radius 2.8 and moment of inertia 920. The platform rotates without friction with angular velocity 1.78. The person walks radially to the edge of the platform. Compute a..
If the ball is released from rest at a height of 0.78m above the bottom of the track on the no-slip side, what is its angular speed when it is on the frictionless side of the track? suppose the ball is a solid sphere of radius 2.3cm and mass 0.14k..
assume that for the couple in, you were told that the girl's mass was two-thirds that of the boy. The boy has a velocity of v = +0.61 m/s. What would be the girl's velocity in this case.
A 200, 47.0 cm-diameter turntables rotate on frictionless bearings at 70. A 24.0 block sits at the center of the turntable. A compressed spring shoots the block radically outward along the frictionless groove in the surface of turntable.
A worker pulls horizontally on a crate on a rough horizontal floor, causing it to move forward with constant velocity. In the figure, force is the pull of the worker and force is the force of friction due to the floor.
A 61.0 kg skier encounters a dip in the snow's surface that has a circular cross section with a radius of curvature of 12.0 m .If the skier's speed at point A is 7.50 m/s (before entering dip), what is the normal force exerted by the snow on the skie..
The two forces in each pair could have different physical origins (for instance, one of the forces could be due to gravity, and its pair force might be due to friction or electric charge).
suppose that we could use the energy released when 5 g of antimatter annihilates 5g of matter to lift a mass 3 km from the Earth's surface. how much mass can we lift? answer in unites of kg.
Two objects are charged and their centers are separated by 31.6 cm. Object A is charged to 61 nC and object B is charged to 54 nC. What is the magnitude of the electrostatic force between them.
A 9.0 Kg box of oranges slides from rest down a frictionless incline from a height of 5.0 m. A constant frictional force, introduced at point A, brings the block to rest at point B, 19 m to right of point A. What is the velocity of the box just be..
What velocity would a proton need to circle Earth 1400 km above the magnetic equator, where Earth's magnetic field is directed horizontally north and has a magnitude of 4 x10-8 T .
