A 5.00 kg box is pulled by a rope with a force of 25.0 N. Determine the acceleration of the boxes. The coefficient of friction between the ground and the box is 0.120.
A steel washer is suspended inside an empty shipping crate from a light string attached to the top of the crate. The crate slides down a long ramp that is inclined at an angle of 39 degrees above the horizontal. The crate has mass 244 kg .
assume that for the couple in, you were told that the girl's mass was two-thirds that of the boy. The boy has a velocity of v = +0.61 m/s. What would be the girl's velocity in this case.
A stationary radar operator determines that a ship is 13km south of him. An hour later the same ship is 23km southeast. If the ship moved at constant speed and always in same direction, what was its velocity during this time? (Hint: Take the origi..
