Aboy flying a kite is standing 30 ft from a point directly under the kite. if the string to the kite is 50 ft long, what is the angle of elevation of the kite (the angle between the ground where the boy is standing and the kite string)?

Aturntable a is built into a stage for use in a theatrical production. it is observed during a rehearsal that a trunk b starts to slide on the turntable 10 s after the turntable begins to rotate. knowing that the trunk undergoes a constant tangential acceleration of 0.31 m/s2, determine the coefficient of static friction between the trunk and the turntable.

Determine the moment of the force f about an axis extending between a and c. express the result as a cartesian vector. a is at the origin, c is at (4,3,0) and f = (4i + 12j -3k) lb coming out of b (4,3,-2).

Acar is traveling 35 mph on a smooth surface . if a balanced force is applied to the car what happens?
