What angle did the hawk make with the horizontal throughout its descent? For how long did the mouse enjoy the free fall.
A loudspeaker of mass 21.0 {rm kg} is suspended a distance of h = 2.40 {rm m} below the ceiling by two cables that make equal angles with the ceiling. Each cable has the length of l = 3.90 {rm m}.
A 20.00 kg child is on a swing that hangs from 3 m long chains. What is her maximum speed if she swings out to a 45.0 o angle.
find speed at which the ball left the quarterback's hand.
In static equilibrium a spring is stretched 0.25 m by a hanging mass. If the system is initially moved up to the unstretched position and released with zero velocity, determine position of the mass (in m) after 4.2s. Take the equilibrium position ..
