A space traveler weighs 550 N on earth. What will the traveler weigh on another planet whose radius is three times that of earth and whose mass is twice that of earth?
1____________ N
A crate is sliding down a ramp that is inclined at an angle of 59.1° abovethe horizontal. The coefficient of kinetic friction between thecrate and the ramp surface is 1.018. Findthe acceleration of the moving crate.
1____________ m/s2
A 258 kg log is pulled up a ramp by meansof a rope that is parallel to the surface of the ramp. The ramp isinclined at 30.0° with respect to the horizontal. Thecoefficient of kinetic friction between the log and the ramp is0.840, and the log has an acceleration of0.700 m/s2. Find the tension in the rope.
