A solid wheel (solid cylinder) with mass 2.5 kg and a radius of 0.50 meter starts rotating (about an axis thru its center and perpendicular to the plane of the solid cylinder) from rest and has a constant angular acceleration of 2.5 radians/second^2. After 6.0 seconds the wheel has an angular velocity of 15 radians/second. Determine the torque required to produce this motion.
A person looks horizontally at the edge of a swimming pool. If its length is 5.00m, and the pool is filled to the surface, to what depth (in m) could observer see? For water is 1.33).
Ice at -10.2 °C and steam at 136 °C are brought together at atmospheric pressure in a perfectly insulated container. After thermal equilibrium is reached, the liquid phase at 53.0°C is present.
A 20 g ball is fired horizontally with initial speed v_0 toward a 110 g ball that is hanging motionless from a 1.10 m-long string. The balls undergo a head-on, perfectly elastic collision, after which the 110 g ball swings out to a maximum angle t..
The ball is free from rest with the line taut and horizontal (θ = 90.0°). At what angle θ (measured from the vertical) would the fishline break.
A 400 kg car sits 2 m to the right of a fulcrum assume car is on a weightless rod, how far to the left of the fulcrum should an effort of 200 N be applied to keep the system in quilibrium.
