Consider three force vectors Ē with magni- tude 42 N and direction 130°, Ē, with mag-
nitude 22 N and direction -59°, and Hz with
magnitude 14 N and direction 46º. All direc-
tion angles are measured from the positive
axis: counter-clockwise for 0 > 0 and clock-
wise for Ꮎ < 0.
What is the magnitude of the resultant vec-
tor = R1 + R2 + 73 ?

Carbon-14 is a radioactive element that undergoes beta decay. which force is responsible for allowing carbon-14 to become stable? electromagnetic gravitational weak nuclear strong nuclear

The system is released from rest with the cable taut, and the homogeneous cylinder does not slip on the rough incline. determine the angular acceleration of the cylinder and the minimum coeffi cient s of friction for which the cylinder will not slip.

Which of the following situations is impossible? a) an object has velocity directed east and acceleration directed east. b) an object has zero velocity but non-zero acceleration. c) an object has constant non-zero velocity and changing acceleration. d) an object has velocity directed east and acceleration directed west. e) an object has constant non-zero acceleration and changing velocity.
